[2] IMG was founded in 1960 in Cleveland, Ohio, by Mark McCormack, an American lawyer who spotted the potential for athletes to make large incomes from endorsement in the television age.

He signed professional golfers Arnold Palmer, Gary Player and Jack Nicklaus as his first clients who collectively are known as The Big Three.

In November 2007, IMG acquired Kentucky-based Host Communications, which had multiple business units with services ranging from sports marketing and broadcasting to the management of associations and non-profit organizations.

[11] In October 2024, IMG agreed to be purchased by another one of Endeavor's subsidiaries, TKO Group Holdings, as part of a $3.25 billion deal, with the transaction expected to close in the first half of 2025.

[12] IMG's Media Division produces, develops and executes multi-channel distribution strategies for federations, associations and events working with major global broadcasters, channels and platforms.
