a 17.5 rating; NBC was down slightly to 13.9. On October 18, 1981, Game 5 of the National League Championship Series between the Los Angeles Dodgers and Montreal Expos, which was supposed to be televised on NBC that Sunday afternoon, was postponed due to snow. The cancellation of that game allowed CBS to achieve record breaking television viewership levels for a regular-season professional football broadcast. It was rated as the most watched afternoon of regular-season NFL football broadcasts on a single network in television history. In 1981, CBS introduced a new opening theme for the NFL games, a peppy, fanfare-styled theme (with a tempo reminiscent of the disco style still somewhat popular at the time) that remained in use until partway through the 1986 season. The patriotic-style opening title sequence showed the Stars and Stripes of the U.S. flag morphing into the words "National Football League." That same year, CBS Sports standardized its on-screen graphics for all of its telecasts; prior to this, each director in charge for each game used a different look.

At the time CBS had reshuffled their #1 team lineup as Summerall's longtime broadcast partner Tom Brookshier was moved into a play-by-play role (teamed with former Detroit Lions legend Wayne Walker, at the time the sports director for CBS affiliate KPIX), and it was not immediately clear if Summerall was going to keep his position or if #2 play-by-play man Vin Scully, whose contract was
