now anxious to promote Dick Enberg (who hosted NBC's pre-game and post-game coverage of Super Bowl XIII) to the lead NFL position, Gowdy moved over to CBS to call more football, as well as baseball on radio. The teams of Dick Enberg and Merlin Olsen and Curt Gowdy and John Brodie began 1978 as co-head crews. But the unofficial passing of the torch happened on Thanksgiving, when Enberg and Olsen covered the Denver-Detroit game, while the following Sunday, Gowdy and Brodie covered the Seattle-Oakland game. Len Dawson joined Dick Enberg in covering the Houston-Miami wild card game, and Charlie Jones in the Houston-New England divisional playoff game. Dawson did not work Week 15 due to mourning the death of his wife. Merlin Olsen would join Curt Gowdy and John Brodie for that season's AFC Championship Game. NBC's January 21, 1979 telecast of Super Bowl XIII between the Pittsburgh Steelers and Dallas Cowboys was viewed in 35,090,000 households, by an estimated 96.6 million fans. The game – called by Curt Gowdy on play-by-play, with Merlin Olsen and John Brodie on color commentary and Dick Enberg serving as the pregame host for the broadcast with Bryant Gumbel and Mike Adamle as sideline reporters – was Gowdy's seventh and final Super Bowl telecast, and his last major event for NBC before moving to CBS later in 1979. Enberg had essentially succeeded Gowdy as NBC's lead NFL play-by-play announcer in the 1978 regular season, and network producers did not decide until nearly the last minute which of them would conduct play-by-play for that year's Super Bowl. NBC preceded the game with the first network broadcast of Black Sunday, a 1977 film that depicts a terrorist attack on a fictitious Super Bowl game in the Orange Bowl between Pittsburgh and Dallas (and which utilized footage shot during Super Bowl X). The pregame festivities featured the Dallas Cowboys Cheerleaders and several military bands. The Colgate Thirteen performed the national anthem. The coin toss ceremony featured Pro Football Hall of Famer and longtime Chicago Bears owner/head coach George Halas. The national radio broadcast of Super Bowl XIII was carried by the CBS Radio Network, with Jack Buck and Hank Stram calling the action. Locally on radio, Verne Lundquist and Brad Sham called the game for the Cowboys on KRLD in Dallas, while Jack Fleming and Myron Cope called it for the Steelers on WTAE in Pittsburgh. A
