Roundup

Roundup is a glyphosate-based developed by and first introduced to the market in as a non-selective, systemic broad-spectrum killer that inhibits the enzyme essential for . Widely adopted in , , and non-crop areas, its efficacy surged after the 1996 commercialization of glyphosate-resistant , enabling simplified management and practices that reduce and improve water retention. By the 2010s, formulations like Roundup accounted for the majority of use in major U.S. crops such as corn and soybeans, with global applications exceeding 1.8 million tons annually by 2014 due to its cost-effectiveness and environmental breakdown relative to alternatives. Despite these agricultural benefits, Roundup has faced significant over potential human health and ecological effects, including claims of carcinogenicity; the Agency for Research on Cancer deemed "probably carcinogenic" in 2015 based on limited mechanistic and animal evidence, prompting thousands of lawsuits alleging causation, whereas the U.S. Agency's evaluations, incorporating over twice as many carcinogenicity studies, have consistently found it "not likely to be carcinogenic to humans" at typical exposure levels, attributing differences to IARC's hazard-focused approach versus risk assessments that include real-world use patterns. Regulatory affirmations by bodies like the EPA and emphasize 's low toxicity profile when labels are followed, though concerns persist about adjuvants, , and indirect environmental cycling from overuse.

General meaning

Gathering and collection

The term "roundup" refers to the act of systematically gathering or collecting dispersed animals, people, or items into a centralized group, often for , counting, or processing. As a noun derived from the "round up," it first appeared in general English around the 1610s to denote collecting into a , with specific application to by 1847 and the cattle-drive sense of the noun by 1869. This usage emerged in 19th-century amid the expansion of open-range ranching in the . In ranching, roundups primarily involve assembling or other scattered across large pastures, a practice central to the during the post-Civil era. Cowboys on horseback would encircle herds, driving them to a central corral for , , veterinary checks, and selection for market or drives; these events occurred biannually in spring and fall to manage seasonal grazing and reproduction. In the 1870s, as the range boomed, roundups preceded major trail drives like those along the , where millions of —estimated at 27 million head driven northward from the 1860s to 1880s—were gathered for shipment to railheads in . Pre-industrial methods relied on and labor, often requiring teams of 10–20 cowboys to cover hundreds of square miles over days or weeks, limited by terrain and weather. Modern ranching has shifted toward mechanized and aerial techniques for greater scale and speed, particularly on vast operations managing thousands of head. Helicopters, adopted since the mid-20th century, enable pilots to herd by hovering low and directing movement from above, reducing gathering time by up to 90% compared to horseback methods and minimizing needs from dozens to a handful. This efficiency supports operations like those in or , where aerial roundups cover remote deserts or forests, lowering labor costs and stress on animals while allowing year-round monitoring via integrated technologies such as GPS collars. Empirical comparisons show traditional roundups processed herds at rates of 100–500 head per day per crew, versus modern aerial methods handling 1,000–5,000 head in hours, though they require skilled pilots and fuel investments. Beyond livestock, "roundup" extends to human contexts, such as law enforcement operations to apprehend suspects en masse, a tactic known as a "dragnet" and prevalent in early American urban policing from the late 19th century onward. Historical examples include coordinated sweeps during Prohibition-era raids in the 1920s, where police gathered dozens of individuals in single operations for questioning or arrest. In event organization, it denotes compiling or assembling participants or items, as in community gatherings or news summaries, though rooted in the same principle of aggregation for efficiency.

Herbicide

History and development

, the active ingredient in Roundup, was discovered as a by chemist John E. Franz in 1970 during research into phosphorus-containing compounds for potential agricultural applications. filed patents for its herbicidal use in 1971, with U.S. Patent 3,799,758 granted on March 26, 1974, covering N-phosphonomethylglycine () formulations. The U.S. Environmental Protection Agency registered for use that same year, enabling initial commercialization as Roundup, a non-selective, broad-spectrum effective against annual and perennial weeds. Early adoption focused on pre-plant and post-emergence applications in non-crop areas, orchards, and fallow fields, with significant U.S. sales beginning in 1976. The herbicide's efficacy and relatively low cost drove rapid , particularly after Monsanto's expiration in 2000 allowed generic production. A pivotal development occurred in 1996 with the introduction of soybeans, genetically modified to tolerate , allowing post-emergence spraying without crop damage and facilitating simplified weed management. This integration spurred widespread adoption of practices, which minimize soil disturbance to reduce erosion—studies indicate glyphosate-enabled no-till systems can cut soil loss by up to 90% compared to conventional tillage while preserving . By the mid-2000s, crops expanded to corn, , and other staples, amplifying use; global applications exceeded 8 billion kilograms (approximately 18 billion pounds) cumulatively by the , with annual volumes reaching hundreds of millions of kilograms. In 2018, Bayer acquired for $63 billion, consolidating control over production and seed technologies, which further entrenched Roundup's market dominance amid rising demand from conservation tillage and resistant crop systems. This merger built on decades of that transformed from labor-intensive mechanical methods to chemical precision, though it also intensified scrutiny over long-term dependency on a single herbicide .

Composition and mechanism of action

Roundup herbicide formulations contain (N-(phosphonomethyl)), typically formulated as the salt, as the primary at concentrations ranging from 41% to 50% by weight in many products. These formulations include inert ingredients, notably such as (POEA), which enhance efficacy by facilitating penetration through plant cuticles and improving adhesion to leaf surfaces. Glyphosate inhibits the enzyme 5-enolpyruvylshikimate-3-phosphate synthase (EPSPS), a key component of the responsible for synthesizing essential aromatic (, , and ) in . This pathway is absent in animals, conferring selectivity to as a that targets without directly affecting animal via the same . By competitively to EPSPS and preventing the incorporation of phosphoenolpyruvate into shikimate-3-phosphate, disrupts downstream protein, , and production, ultimately leading to cessation of growth and death. Upon foliar application, is absorbed primarily through leaves and green stems within hours, with uptake enhanced by like POEA. It is then translocated systemically via the to meristematic tissues, , and other sites of active , where it accumulates and exerts its inhibitory effects. Empirical studies demonstrate that this process results in and visible within 2-4 days, with complete mortality of susceptible weeds typically occurring in 7-14 days, varying by plant species, environmental conditions, and application rate. In response to ongoing litigation, Bayer discontinued glyphosate-based formulations for residential consumer products in the U.S. market by 2024, introducing an "Exclusive Formula" line relying on alternative active ingredients such as , fluazifop, imazapic, and , while agricultural and professional-use variants continue to feature . These changes do not alter the core biochemical mechanism for glyphosate-containing products but reflect formulation adjustments to address non-efficacy concerns.

Agricultural uses and economic impact

Glyphosate, the active ingredient in Roundup, is primarily applied in as a non-selective for broad-spectrum . It is commonly used for pre-plant burndown treatments to eliminate existing vegetation before seeding such as corn and soybeans, allowing for timely planting without mechanical interference. In glyphosate-tolerant genetically modified () , including over 90% of U.S. soybeans and corn acres planted with herbicide-tolerant varieties by the mid-2020s, it enables post-emergence applications during the , targeting weeds while sparing the crop. This flexibility has facilitated the of practices, reducing and fuel use by minimizing plowing. Economically, glyphosate has driven significant productivity gains by simplifying weed management and lowering input costs. In the U.S., its integration with GM crops has contributed to yield increases of 10-30% in major row crops through effective weed suppression, while cutting labor and machinery expenses associated with alternative methods like tillage or multiple herbicide passes. Globally, the herbicide's role in enabling no-till and reduced-till systems has been estimated to save farmers billions annually in operational costs, with U.S. Department of Agriculture analyses highlighting its value in maintaining high output amid rising input prices. These benefits have supported expanded cultivation of staple crops, bolstering food supply stability and export competitiveness, though dependence on a single mode of action has prompted shifts toward diversified strategies. Advancements in have enhanced glyphosate's efficiency by enabling targeted applications that minimize off-target use and environmental drift. Drone-based systems, equipped with , allow for spot-spraying on weed-infested areas within fields, reducing overall volume by up to 90% compared to broadcast methods in some trials. This technology integrates with global positioning systems for variable-rate application in row crops, preserving glyphosate's utility while addressing overuse concerns. Weed resistance to , documented in over 50 globally by 2025, poses a key challenge, with more than 30 resistant affecting U.S. cropland and leading to yield losses of 20-50% in unmanaged fields. Resistance arises from repeated exclusive reliance, amplifying selection pressure, but (IPM) mitigates this through , cover cropping, and residual herbicides alongside glyphosate. Such approaches restore efficacy, with extension services reporting sustained control when or mechanical methods supplement chemical use, balancing economic gains against evolving dynamics.

Safety evaluations and regulatory approvals

The (EPA) has conducted multiple reviews of , the active ingredient in Roundup, concluding in its 2020 assessment that it is "not likely to be carcinogenic to humans" based on evaluations of animal carcinogenicity studies, data, and human showing no consistent evidence of cancer risk. This determination aligns with prior EPA findings from 2017 and emphasizes that glyphosate does not meet criteria for carcinogenicity classification under agency guidelines, drawing from chronic rodent studies where tumors observed were not dose-dependent or biologically plausible for humans. The Joint Meeting on Pesticide Residues of the (WHO) and (FAO), known as JMPR, evaluated in 2016 and established an (ADI) of 0–1 mg/kg body weight, affirming that dietary exposures at labeled application rates pose no appreciable health risk to consumers, supported by data indicating low acute and . JMPR's review incorporated over 100 studies on , , and long-term effects, concluding insufficient for genotoxic or carcinogenic potential relevant to human exposure levels from approved uses. In the , glyphosate's approval was renewed in 2017 for five years following assessments by the (EFSA), which found no critical areas of concern for when used as labeled, and extended in 2023 for ten years until December 2033, subject to restrictions on non-agricultural uses and requirements for further data on certain metabolites. These renewals relied on harmonized risk assessments privileging empirical data from mammalian studies, where no-observed-adverse-effect levels (NOAELs) ranged from 100–1,000 mg/kg/day across species, far exceeding typical exposures. Occupational exposure for applicators, such as farmers, is estimated at margins of exceeding 1,000-fold below these NOAELs, with dermal and doses typically under 0.01 mg/kg body weight per application when using protective equipment. Regulatory approvals also incorporate environmental safety evaluations, with glyphosate's soil half-life varying from 2 to 197 days depending on microbial activity, , and , averaging around 30–47 days in field conditions, which supports its classification as having low persistence risk. (USGS) monitoring data indicate minimal contamination, with detections below 1 µg/L in most aquifers, reflecting low potential due to strong soil adsorption and lack of in non-target organisms. These factors underpin approvals emphasizing labeled use to minimize off-site movement.

Health controversies and scientific debates

In 2015, the International Agency for Research on Cancer (IARC), a branch of the , classified as "probably carcinogenic to humans" (Group 2A), citing limited evidence of associations with (NHL) in humans from occupational exposure studies and sufficient evidence of carcinogenicity in experimental animals. This classification relied primarily on case-control studies with relative risks around 1.4 for high-exposure groups, but excluded or underweighted prospective cohort data available at the time. Critics have noted that IARC's process involved editing drafts to downplay findings of non-carcinogenicity, potentially reflecting selective emphasis on mechanistic and animal data over human epidemiology. Contrasting with IARC, large-scale prospective cohort studies, such as the involving over 54,000 pesticide applicators followed for more than 20 years, found no statistically significant association between exposure and NHL incidence, with hazard ratios near or below 1.0 even for the highest exposure quartiles (adjusted HR 1.09, 95% CI 0.80-1.50). Updated meta-analyses incorporating data and other cohorts, including over 300,000 participants, similarly report no overall elevated NHL risk from (pooled RR 1.03, 95% CI 0.95-1.12), with relative risks often under 1.1 in high-quality epidemiological assessments. These findings align with evaluations by agencies like the U.S. Environmental Protection Agency, which concluded is "not likely to be carcinogenic to humans" based on comprehensive reviews prioritizing human data over limited mechanistic evidence. Claims of other health effects, such as disruption or endocrine interference, stem largely from or high-dose animal models but lack replication in studies at environmentally relevant exposure levels (typically below 1-2 mg/kg/day for applicators). For instance, while inhibits certain bacterial enzymes like EPSPS in lab settings, rodent studies at doses exceeding equivalents show transient shifts without consistent links to disease outcomes like or . Endocrine effects, including altered signaling observed in cell cultures or at concentrations 100-1000 times above typical exposure, do not translate to epidemiological signals of reproductive or disruption in occupationally exposed populations. Formulation-specific concerns arise from surfactants like (POEA) in Roundup products, which exhibit higher to organisms and amphibians than alone, with LC50 values 10-100 times lower in some assays. poisoning cases involving high ingestion (e.g., >100 mL) highlight surfactant contributions to gastrointestinal and renal effects, though itself shows low acute mammalian toxicity (oral LD50 >5000 mg/kg). Prior to 's introduction in 1974, herbicides like and posed greater risks due to higher persistence and , with enabling reduced overall volumes and substitution for more hazardous alternatives. Despite minority reports of or developmental effects from select lab studies, causal links remain unsubstantiated in human cohorts, underscoring the primacy of epidemiological null findings over preliminary mechanistic hypotheses. Litigation against (acquired by in 2018) over Roundup escalated following the International Agency for Research on Cancer's (IARC) 2015 classification of as "probably carcinogenic to humans," prompting thousands of U.S. plaintiffs to allege that the herbicide caused non-Hodgkin's lymphoma and that the company failed to warn of risks. These failure-to-warn claims under state law have formed the core of suits, despite ongoing EPA approvals affirming glyphosate's for use. The first bellwether trial, in state court, resulted in a June 2018 jury verdict awarding the plaintiff $39 million in compensatory damages and $250 million in , totaling $289 million, for failing to warn of cancer risks from Roundup exposure while working as a school groundskeeper. The award was later reduced by the trial court to $78 million, a decision upheld on appeal in 2020, though the liability finding stood, setting a that fueled subsequent filings exceeding 192,000 claims by mid-2025. Bayer has resolved approximately 131,000 claims through settlements or ineligibility determinations as of July 2025, committing about $11 billion overall, including a 2020 master settlement framework for up to 125,000 cases and additional reserves of $1.37 billion announced in July 2025 to address remaining litigation expected to conclude by 2026. Roughly 61,000 claims persist, primarily in multidistrict litigation, with maintaining a favorable trial record of about 70% defense wins where cases reach juries. In 2025, appellate courts have reinforced defenses in key cases, such as the First Appellate Court's September 18 upholding of a 2023 trial verdict for in Evard v. Monsanto Co., rejecting claims of causation from Roundup exposure in a non-Hodgkin's suit due to insufficient evidence linking the product to the illness. Appeals in other verdicts have frequently cited lacks in general or specific causation, contrasting with plaintiff jury awards that diverge from EPA assessments deeming unlikely carcinogenic at labeled exposures. Legislative responses have emerged in at least 11 states by 2025 to curb suits via Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA) preemption, which bars state requirements exceeding federal labeling standards; enacted laws in (effective July 2025) and (August 2025), alongside bills in , , , , and , aim to dismiss failure-to-warn claims preempted by EPA-approved labels. A pending U.S. review of circuit splits on FIFRA preemption could further limit ongoing claims if it affirms federal supremacy over divergent state tort liabilities.

Livestock and ranching

Practices and techniques

Livestock roundups involve systematically gathering scattered from rangelands into centralized pens or corrals for tasks such as , , , , or preparation for market shipment. Traditional techniques rely on horseback riders who fan out across pastures to locate herds, encircle them using coordinated driving, and direct them toward temporary wings or funnels leading to holding facilities, minimizing stress and scatter. In larger operations on open ranges, these methods ensure efficient collection without excessive dispersal. Modern practices incorporate all-terrain vehicles (ATVs) for faster traversal of rough terrain and helicopters for aerial scouting or herding over vast areas, particularly in remote western rangelands where may roam miles from . Helicopters enable rapid location and gentle pushing of herds, reducing physical on ground crews while covering distances impractical on foot or horseback alone. Roundups typically occur seasonally, with spring gatherings around May for newborn calves before turning herds onto summer pastures, and fall events in for and prior to winter feeding. On U.S. public lands managed by the (), which authorize for approximately 1.5 million across 155 million acres, these operations align with permit conditions to prevent and maintain allotment health standards. Advancements like GPS-enabled collars and tags have streamlined operations by providing real-time herd location data, enabling smaller teams to monitor and direct remotely and reducing labor requirements from historical levels of 10 or more per major drive—sufficient for herds of 3,000 head—to as few as 2-5 workers in tech-assisted scenarios. This shift lowers costs associated with large crews while improving precision in grazing management and loss prevention.

Historical and cultural significance

Cattle roundups emerged in the mid-19th century American West, particularly in and , as essential practices for gathering semi-feral herds descended from Spanish longhorns and early colonial stock for , , and preparation for market drives. In , where vast unclaimed herds roamed after the , roundups enabled ranchers to consolidate cattle for trailing northward along routes like the , which spanned over 2,000 miles across nine states starting in the 1870s. ranching, beginning in the 1850s in western valleys, incorporated similar techniques by the 1860s, with the first Texas-to- drive in 1866 supplying mining camps and expanding beef production northward. These operations were pivotal to frontier economics, funneling an estimated six million head to railheads for eastern markets, where beef prices fetched up to ten times values, spurring town growth in places like Abilene and Dodge City. Roundups also fostered cultural icons, evolving into public spectacles that celebrated ranching skills. Events like Cheyenne Frontier Days, founded in 1897 in Wyoming, originated from informal cowboy roundups and featured bronco busting, steer roping, and pony races as demonstrations of frontier prowess. These gatherings romanticized the cowboy archetype, embedding roundup traditions in American identity through rodeo competitions that persist today. By the post-1950s era, traditional roundups waned in the U.S. due to barbed-wire fencing enclosing ranges from the 1880s onward and truck hauling supplanting horse drives by the 1970s, shifting to more mechanized herd management. However, analogous mustering practices endure in , where vast stations rely on historical methods for gathering mobs on properties exceeding millions of acres, as seen in epic 19th- and early 20th-century treks like the 2.5-year drive to the region.

Military and law enforcement

Military operations

Operation Roundup was the codename for a proposed Allied invasion of German-occupied northern scheduled for 1943 during . The plan, developed in early 1942 primarily under U.S. initiative, aimed to establish a major second front in by landing approximately 48 divisions—30 American and 18 British—across the from . It formed the middle phase of a three-stage strategic offensive against , preceded by the buildup of U.S. forces in the under and followed by a push into . Approved by President on April 1, 1942, the operation reflected American pressure, led by Army Chief of Staff , for an early direct assault on Fortress to relieve Soviet burdens on the Eastern Front. However, British and his Chiefs of Staff harbored significant reservations, citing inadequate landing craft, air superiority deficits, and risks of high casualties against fortified defenses. These concerns, coupled with logistical constraints, prompted Churchill to advocate for peripheral strategies, ultimately swaying Roosevelt toward —the November 1942 invasion of —instead. By mid-1942, Anglo-American divergences escalated at conferences like the July Anglo-American Chiefs of Staff meeting, where Roundup's timeline was questioned amid competing demands for Mediterranean operations. The plan was formally deferred at the in January 1943, with resources redirected to the larger, more feasible executed on June 6, 1944. Despite its cancellation, Roundup's deliberations shaped Allied command structures, force deployments, and the eventual D-Day strategy, highlighting tensions between U.S. advocates for bold continental invasion and British preferences for incremental attrition. Declassified documents reveal it influenced postwar analyses of "Germany First" prioritization, underscoring how early feasibility assessments averted potential disasters. Subsequent military operations bearing the name "Roundup" have typically denoted targeted advances or clearances rather than grand invasions. In Iraq's Diyala Province, Operation Marne Roundup, launched December 15, 2007, by Multi-National Division-Center forces, aimed to disrupt networks through joint U.S.-Iraqi raids and seizures of insurgent safe houses, resulting in over 100 enemy combatants killed or detained. Similarly, in , a U.S.-led operation named Roundup in eastern involved dozens of airstrikes and ground maneuvers to dismantle remnants, accelerating the group's territorial collapse in the region. These later uses emphasize operational consolidation over strategic overhauls, distinct from the WWII plan's scale. No major military campaigns have directly incorporated the herbicide Roundup (glyphosate-based) under that operational name, though defoliation efforts from 1962–1971 parallel chemical vegetation control concepts; these relied on agents like , spraying nearly 19 million gallons without glyphosate involvement.

Law enforcement applications

In , a roundup refers to a coordinated, large-scale involving multiple agencies to apprehend suspects, , or members of criminal networks, often in urban settings to disrupt or fugitive activity. These operations typically involve pre-planned raids, , and simultaneous arrests to minimize resistance and flight risks, drawing on shared from , state, and local entities. Historical precedents include the FBI's intensified efforts in under Director to combat Depression-era gangsters, such as coordinated pursuits leading to the capture of figures like in 1934 and the dismantling of gangs through warrant-based arrests across multiple jurisdictions. Empirical data from the FBI highlights the effectiveness of modern multi-agency roundups in reducing populations and . For instance, in Operation No Escape, a 2025 collaboration between the FBI and U.S. Marshals Service, authorities apprehended 177 s over six weeks, including 28 violent offenders wanted for and , demonstrating high capture rates in targeted sweeps. Similarly, a FBI Pittsburgh-led operation in October 2025 resulted in 19 arrests of violent s during a five-day effort, contributing to broader metrics where such initiatives have cleared thousands from wanted lists annually, correlating with localized drops in and outstanding warrants. In Connecticut's segment of Operation No Escape, 84 s were taken into custody by August 2025, underscoring the operational success in high-density urban areas. Post-9/11 roundups exemplify application against perceived threats, with the FBI's investigation leading to over 1,000 arrests in the initial sweeps for and -related violations, though many lacked direct terror links and faced for low rates on substantive charges. These operations prioritized rapid detention based on intelligence tips, reducing immediate risks but prompting debates over efficacy, as only a fraction resulted in convictions per Department data. Legally, roundups must adhere to Fourth Amendment protections against unreasonable seizures, requiring particularized for each —either via judicial warrants or warrantless if supported by exigent circumstances or public observation. Courts have upheld mass operations where individualized suspicion exists, as in for felonies allowing warrantless arrests, but critiques highlight overreach risks in dragnet-style sweeps without warrants, potentially violating particularity requirements and leading to suppressed evidence. Balanced against this, success metrics show crime reductions, such as plummeting murder rates in areas post-fugitive apprehensions, justifying procedural rigor over blanket prohibitions.

Media and journalism

News summaries and formats

News roundups in consist of curated summaries compiling key events from multiple sources into concise briefs, often structured chronologically or thematically to provide an overview of daily developments. This format prioritizes brevity and relevance, typically limiting each item to essential facts such as dates, locations, and outcomes, while avoiding in-depth analysis reserved for standalone reports. In television news, roundups originated with the expansion of scheduled broadcasts in the 1950s, evolving from radio summaries to visual formats that condensed global and national headlines into 15-30 minute segments. The aired its first televised news bulletin on , establishing a model of impartial aggregation that influenced subsequent networks by focusing on factual recaps without editorializing. , launching on June 1, 1980, as the first 24-hour cable news channel, integrated roundups into its continuous cycle, with sister service Headline News emphasizing headline-style summaries updated hourly to cover breaking events efficiently. These practices reduced viewer time investment while maintaining broad coverage, adapting to live reporting demands during events like elections or crises. The digital era shifted aggregation toward algorithmic curation, exemplified by , which launched on September 22, 2002, and initially drew from 4,000 sources to cluster similar stories and personalize feeds based on user queries and reading history. Unlike manual TV editing, these platforms employ to process vast volumes—over 25,000 publishers by 2014—filtering duplicates and prioritizing recency to handle . Economic analyses indicate that such aggregators lower barriers to news access, increasing overall consumption by directing traffic to originals while minimizing redundancy through topic-based grouping. Studies on aggregator impacts highlight their role in enhancing efficiency, with evidence showing they boost attention allocation to diverse topics by summarizing snippets that encourage deeper engagement, thereby sustaining reader interest amid fragmented media landscapes. For instance, aggregator use correlates with higher selective exposure to varied content, countering echo chambers by surfacing cross-source perspectives in compact formats. This mechanism supports retention by streamlining discovery, as users spend less time scanning disparate outlets for comprehensive updates.

Film

The Roundup is a South Korean action crime film series centered on Detective Ma Seok-do, portrayed by Ma Dong-seok, who leads efforts to apprehend violent criminals through coordinated police operations. The franchise began with the precursor The Outlaws in 2017 and continued with The Roundup in 2022, which depicts Ma traveling to Vietnam to extradite a suspect amid murders of Korean tourists by a serial killer, blending brutal action sequences with comedic elements. This installment grossed nearly $100 million at the Korean box office, becoming the highest-earning film of 2022 there with over 13 million admissions. Subsequent entries, The Roundup: No Way Out (2023) and The Roundup: Punishment (2024), follow Ma investigating drug trafficking and online gambling rings, respectively, maintaining the series' focus on high-stakes captures while incorporating international elements like Vietnamese and Japanese antagonists. Critical reception has been positive for its visceral fight choreography, with The Roundup holding a 96% approval rating on Rotten Tomatoes based on 26 reviews praising its energetic pacing despite formulaic plotting. Earlier films titled The Round-Up employ the term in historical contexts of mass apprehensions. Miklós Jancsó's 1966 drama The Round-Up portrays Austrian forces interning suspected Hungarian partisans in a remote camp following the failed 1848 revolution, using long takes and minimal dialogue to explore coercion and betrayal among prisoners. The film received acclaim for its innovative cinematography and political depth, earning a 7.5/10 average user rating on from over 3,600 votes and recognition as a landmark in Eastern European cinema. In a World War II setting, the 2010 French film La Rafle (The Roundup), directed by Roselyne Bosch, dramatizes the 1942 in , where French police arrested over 13,000 Jews under Nazi orders, focusing on child survivor Jo Weisman amid the chaos of internment and deportation. It garnered mixed reviews, with a 57% Rotten Tomatoes score from 35 critics noting its earnest intent but uneven execution in conveying historical horror. Western films often literalize "roundup" as or pursuits. The 1920 The Round-Up, directed by George Melford and starring "Fatty" Arbuckle as an inept , follows his bumbling efforts to capture desperados in a frontier town, incorporating amid ranching motifs. It holds a 6.1/10 rating from 244 users, valued today for preserving early humor and Arbuckle's pre-scandal popularity. Similarly, Lesley Selander's 1941 B-Western The Round Up features as a rancher thwarting at a , emphasizing themes of and protection, with modest contemporary reception reflected in its 6.1/10 score. Short films like the 1920 British Roundup document real-life American drives, capturing corralling herds in open ranges, providing empirical footage of early 20th-century ranching practices without embellishment.

Music

"Roundup Lullaby," a song with lyrics by South Dakota poet Badger Clark first published in 1924, depicts the nighttime calm after a , evoking the ranching era's rhythms with lines about weary and grazing herds under the stars. Set to music by various artists, it was recorded by in the mid-20th century as part of his western-themed repertoire, preserving oral traditions of frontier life where roundups centralized practices essential to 19th-century American cattle operations. The song's enduring appeal in circles ties to its authentic portrayal of ranching hardships, performed by singers like Edwards to maintain of seasonal gatherings. In 1962, and the Orchestra released the album Pops Roundup, featuring orchestral arrangements of cowboy and western folk tunes such as "" and "," which indirectly reference roundup logistics through themes of open-range herding. This instrumental collection, issued by RCA Victor, introduced classical audiences to ranching-inspired melodies, drawing from 19th-century folk sources that romanticized the cattleman's annual drives across the , where crews of 20-50 men managed thousands of head. The 1999 song "Woody's Roundup," composed by and performed by the cowboy trio Riders in the Sky for Disney-Pixar's , blends and twangy guitar in a playful homage to television westerns, name-checking characters like cowgirl Jessie amid fictional cattle herding antics. Riders in the Sky, formed in 1971 and known for preserving cowboy music traditions, infused the track with authentic elements rooted in culture, amassing over 3 million views by evoking roundup camaraderie. Later, bluegrass band The Rarely Herd issued Roundup, Volume One in 2007, compiling original and traditional tunes like "Preachin' Up a Storm" that echo Appalachian influences on frontier folk, connecting to broader ranching narratives through acoustic instrumentation. A 2025 country release, "Roundup (At the Rodeo)" by Hank Rainbow, captures modern interpretations of events with upbeat rhythms suited to arena performances, released via Terrabyte Music and aligning with contemporary anthems that sustain ranching heritage amid evolving agricultural practices. These works collectively underscore "Roundup" as a in American , from ballads documenting empirical —where roundups optimized and —to stylized tributes reinforcing cultural over mythologized frontiers.

Other media

In , the cattle roundup serves as a recurring motif symbolizing the rigors of frontier ranching life. Owen Wister's seminal novel The Virginian (1902) includes detailed scenes of cowboys riding southward to gather stray cattle, highlighting tensions among the crew during the process. such as Roundup of Western Literature: An Anthology for Young Readers, edited by Oren Arnold, compile excerpts from such works to illustrate the roundup's role in shaping cowboy archetypes. Television Westerns frequently portrayed roundups to evoke the seasonal demands of management. The series , which aired from 1955 to 1975 and drew audiences averaging 20-40 million viewers per episode in its peak years, featured the episode "The Round Up" (Season 2, Episode 4, September 29, 1956), where Dodge City merchants anticipate disorder from arriving cowboys celebrating the end of a roundup. In (1959-1973), operations on the Ponderosa often incorporated roundup sequences amid family dramas, as seen in episodes involving herd gathering before drives, reflecting the show's emphasis on sustainable ranching. These depictions prioritized dramatic conflicts over technical accuracy, drawing from literary traditions while adapting for episodic formats.
