all regular season games for an annual fee of US$4.65 million. CBS also acquired the rights to the championship games for 1964 and 1965 for $1.8 million per game, on April 17, 1964. CBS executive vice president James T. Aubrey, Jr., who on May 9, 1963, warned the network's affiliates the high cost of rights for professional sports could price them off television, nevertheless in January 1964 agreed to pay $28.2 million to air National Football League games for two years, spanning 17 games each season. In an interview with The New York Times, Aubrey said regarding the package, "We know how much these games mean to the viewing audience, our affiliated stations, and the nation's advertisers". Along with obtaining the aforementioned rights to the NFL Championship Game, in April 1964, he agreed to extend the deal for another year for a total of $31.8 million.

Normal programming, including the NFL, was replaced by non-stop news coverage, broadcast without commercials. Half and half format In 1964, CBS experimented with a "half-and-half" format for their announcers.

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,
