the portions which present novel information, such as updated results from daily case counts or new epidemiological models, and then to speed through the dull parts at accelerated playback speed. This can be framed as a novel media consumption modality of instantaneous time shifting. History During a 1955 Hockey Night in Canada broadcast on CBC Television, producer George Retzlaff used a "wet-film" (kinescope) replay, which aired several minutes later.Videotape was introduced in 1956 with the Ampex Quadruplex system. However, it was incapable of displaying slow motion, instant replay, or freeze-frames, and it was difficult to rewind and set index points. The end of the March 24, 1962, boxing match between Benny Paret and Emile Griffith was reviewed a few minutes after the bout ended, in slow motion, by Griffith and commentator Don Dunphy. In hindsight it has been cited as the first known use of slow motion replay in television history. CBS Sports Director Tony Verna invented a system to enable a standard videotape machine to instantly replay on December 7, 1963, for the network's coverage of the US military's Army–Navy Game. The instant replay machine weighed . After technical hitches, the only replay broadcast was Rollie Stichweh's touchdown. It was replayed at the original speed, with commentator Lindsey Nelson advising viewers "Ladies and gentlemen, Army did not score again!" The problem with older technology was the difficulty of finding the desired starting point; Verna's system used audio tones activated as an interesting event unfolded, which technicians could hear during the rewinding process. Replay from analog disk storage was tried out by CBS in 1965, and commercialized in 1967 by the Ampex HS-100, which had a 30-second capacity and freeze frame capability. Instant replay has been credited as a primary factor in the rise of televised American football, although it was popular on television even before then. While one camera was set up to show the overall "live" action, other cameras, which were linked to a separate videotape machine, framed close-ups of key players. Within a few seconds of a crucial play, the videotape machine would replay the action from various, close-up angles, in slow motion. Prior to instant replay, it was almost impossible to portray the essence of an American football game on television. Viewers struggled to assimilate the action from a wide shot of the field, on a small black-and-white television screen. However, as Erik Barnouw says in
