The VHS tape made its debut at the Consumer Electronics Show (CES) in 1977; it was an instant success. VHS was especially revolutionary for athletic coaches, who were previously limited to reel-to-reel equipment when reviewing game film.
VHS brought with it two especially innovative functions: Pause and Rewind. With these two functions, coaches could play the game film, pause at a critical moment, rewind, and show players how it happened. The game would never be the same!
