Pong

Pong is a two-player that simulates , in which players use on-screen paddles to hit a ball back and forth across a simple horizontal line representing a net. Developed by as an title, it was programmed by engineer under the direction of company co-founder and was first installed in a bar in late 1972. The game proved an immediate success, generating far higher earnings than typical machines and prompting to ramp up production. Atari, founded in 1972 by Bushnell and Ted Dabney in Sunnyvale, California, tasked the recent engineering graduate Alcorn with creating Pong as a training exercise, ostensibly for a contract with General Electric that did not actually exist. Alcorn completed the prototype in about three months using discrete TTL integrated circuits, drawing inspiration from earlier demonstrations like the Magnavox Odyssey's tennis game that Bushnell had seen at a trade show. The initial test unit, placed at Andy Capp's Tavern, overflowed with quarters within days, filling the coin box and confirming the game's commercial viability—earning around $40 per day compared to the typical $10 for other machines. This breakthrough led to widespread arcade distribution starting November 29, 1972, and generated approximately $1 million in revenue for Atari in its first full year of sales. Pong's influence extended beyond arcades with the release of a home console version in 1975, produced by for under the Tele-Games brand and featuring a custom to reduce costs. The game's success helped establish the , valued at approximately $189 billion as of 2025, and paved the way for 's console in 1977, which sold more than 30 million units by 1992. Despite legal challenges, including a 1976 lawsuit from over patent infringement that settled by licensing the technology, Pong symbolized the dawn of interactive and inspired countless imitators worldwide.

Gameplay

Mechanics

Pong simulates a competitive two-player game of , in which each player controls a vertical paddle positioned on opposite sides of a central vertical dashed line that represents the net. The players maneuver their paddles up and down to strike a moving square that represents the ball, volleying it back and forth across the net. The primary objective is to score 11 points before the opponent by directing the ball past their paddle, causing it to go on their side of the ; the first player to reach 11 points wins the game. Upon a score, the ball is served from near the toward the player who lost the point. The ball follows a simple physics model, traveling in discrete that approximate 45-degree angles and bouncing off the top and bottom walls of the playfield as well as the paddles. Each collision with a paddle reverses the ball's and adjusts its vertical based on the point of contact—hits near the paddle's center produce straighter returns, while edge hits create sharper deflections simulating —while also incrementally increasing the ball's speed to heighten difficulty. The game's visuals are rendered in black-and-white on an approximately 11-inch vertical , featuring a dashed vertical line for the net, rectangular paddles approximately three units high located at the left and right edges, and a small square for the . Scores for each are displayed as digits above their respective paddles. The original prototype lacked audio effects, but production units incorporated a simple beep tone generated upon paddle hits to enhance feedback.

Controls and Display

In the original arcade version of Pong, each player controlled their rectangular paddle using a single rotary knob mounted on the cabinet, allowing vertical movement along the edge of the playfield to intercept the ball. The game's visuals were generated by a custom discrete logic circuit board employing , without a , utilizing approximately 70 TTL integrated circuits to handle game logic, video signal generation, and . This hardware produced a basic video output displayed on a converted television monitor, simulating a simple court with moving paddles and a square ball that bounced off the paddles and boundaries, occasionally increasing in speed. The was a straightforward wooden enclosure, hand-built for the and units, housing the electronics and featuring an approximately 11-inch black-and-white oriented vertically by rotating it 90 degrees to match the game's portrait-style playfield. Audio output consisted of a rudimentary electronic beep triggered by paddle-ball collisions, produced through a simple oscillator circuit derived from modifications to the vertical sync generator, which was incorporated after the initial to enhance engagement. The original arcade Pong lacked any accessibility features, such as adjustable difficulty or visual aids, and supported only two-player competitive mode with no single-player option against a computer-controlled opponent.

Development and History

Origins and Creation

Pong was conceived in 1972 by Atari co-founders and Ted Dabney as a straightforward electronic game intended for coin-operated machines. The idea emerged from Bushnell's prior experience developing , the first commercially successful released in 1971, which had demonstrated the potential of but also highlighted the need for simpler, more accessible to attract casual players in bars and taverns. Bushnell drew direct inspiration from a demonstration he encountered at a trade show in May 1972, where he tested the Odyssey home console's built-in tennis game, prompting him to envision a video adaptation that could replicate its intuitive appeal on a larger scale. Following the incorporation of on June 27, 1972, Bushnell hired , a recent engineering graduate, as the company's first employee to serve as chief engineer. To familiarize Alcorn with video game hardware, Bushnell assigned him the task of building a based on a rough sketch of the concept, claiming it was for a contract with to develop a game—though no such contract existed—and framing it as a training exercise rather than a commercial priority. This approach allowed Alcorn to experiment with basic paddle-and-ball mechanics using discrete transistor-transistor logic () circuits, emphasizing two-player competition to foster direct head-to-head engagement without complex elements. The design prioritized addictive, uncomplicated to suit bar patrons, stripping away unnecessary features for quick quarters-fed sessions that encouraged repeated plays. Bushnell and Dabney opted for a focus on competitive simplicity—two vertical paddles controlling a bouncing dot on a screen—over multiplayer variants, believing this would maximize replayability and revenue in social settings. Alcorn began work shortly after his hiring in late or early 1972, with the project rooted in the idea pitch amid Atari's formation.

Prototype and Testing

Allan Alcorn, Atari's first engineer, constructed the Pong prototype over approximately three months, beginning in mid-1972. He assembled the hardware using breadboards and a single to generate the video signals, drawing on basic principles to create the game's visuals. The initial version relied entirely on discrete components, including around 75 integrated circuits from the 7400 series, without any (ROM) or (CPU), resulting in rudimentary graphics of simple lines and a dot for the ball. It lacked sound effects at first and used a modified black-and-white , costing $75, as the . On a limited budget for parts, Alcorn exceeded initial constraints with the required chips and sought guidance from Atari co-founder to resolve video synchronization challenges during development. In September 1972, Bushnell and Alcorn installed the prototype at Tavern, a local bar in , to evaluate player engagement. The machine quickly drew crowds, with the coin box overflowing with quarters within weeks due to intense usage, far surpassing expectations for a test unit. Observing players during testing revealed opportunities for refinement; based on this feedback, Alcorn iterated on the design by adding basic sound effects—such as cheering tones for scores and boos for misses—derived from the sync generator, along with adjustments to ball speed and paddle responsiveness to enhance gameplay flow. The prototype's overwhelming success at the convinced Bushnell of its commercial viability, prompting Atari to shift focus from other projects and initiate full-scale production of the .
