During the early 1960s, IMG experienced rapid growth amid the rising popularity of televised sports, expanding its roster beyond Palmer to include fellow golfers Gary Player and Jack Nicklaus in the early 1960s, forming golf's influential "Big Three."

Starting in 1968, IMG negotiated key broadcasting agreements for Wimbledon, leading to subsequent international syndication that grew coverage to 159 countries by the late 20th century. Similarly, he drove worldwide golf broadcasts, producing and selling rights that turned events like major tournaments into global spectacles, with IMG becoming the largest independent producer of televised sports programming outside major networks. McCormack introduced innovative revenue models such as corporate hospitality, launching premium tented enclosures at the British Open in the 1970s to offer executives exclusive access and networking opportunities.
