In 1964, CBS experimented with a ""half-and-half"" format for their announcers. The first half of each telecast would be called by the home teams' commentators while the second half would be done by the visitors' commentators. (This practice would later be revived decades later by the NFL Network when replaying preseason games that were broadcast by local stations as opposed to a national network.) Also in 1964, CBS ditched the concept of using pooled video and split audio feeds. In 1962 and 1963, CBS would provide separate audio for a telecast. For instance, if the Green Bay Packers hosted the Chicago Bears, the telecast would have the same video, Chicago area viewers would hear Red Grange and George Connor call the action. Meanwhile, viewers in Milwaukee and other parts of Wisconsin (Green Bay itself was blacked out) would hear Ray Scott and Tony Canadeo describe the game. Ray Scott was no fan of the separate audio concept and temporarily left CBS for a job calling a regional slate of college football games for NBC. Ultimately, CBS dumped the four man crew and resumed the 1962–63 method for the great majority of games in 1965, 1966 and 1967.
