was introduced during their coverage of the 1988 Seoul Olympics (the network had used Chyron for their graphics prior to Super Bowl XXIII). With the win, the 49ers became the first team to win Super Bowls televised on three different networks (the other two being Super Bowl XVI on CBS and Super Bowl XIX on ABC). Since then, the Washington Redskins (in 1992), the Green Bay Packers (in 1997), the Pittsburgh Steelers (in 2006) the New York Giants (in 2008) the New England Patriots (in 2015) and the Denver Broncos (in 2016) have accomplished this same feat. This was the last outdoor Super Bowl to start earlier than 6:00 p.m. Eastern Time, as it started just after 5:00 p.m. Starting in 1989, NBC commissioned musician (and then-Entertainment Tonight co-host) John Tesh, who would later compose "Roundball Rock" for the forthcoming NBA on NBC broadcasts to compose a new theme, called "Gridiron Dreams" which was used on the network's NFL telecasts until 1991. The versions used on the pre-game show are different from the version supplied on Tesh's albums. For the 1992 season, John Colby composed a theme only used that year through the 1992 AFC Championship Game in which the Buffalo Bills beat the Miami Dolphins 29–10. Week 7's telecast of the Patriots-49ers game (called by Dick Enberg and Bill Walsh) was moved from San Francisco's Candlestick Park to Stanford Stadium in Palo Alto, California following the Loma Prieta earthquake in the Bay Area on October 17. Following the 1989 season, after being demoted to the #2 team alongside Charlie Jones, Merlin Olsen would move over to CBS. Olsen's final telecast for NBC was the divisional playoff game between the Bills and Browns. Meanwhile, Lyle Alzado, who was on the eighth-tier team alongside Fred Roggin, would leave NBC after the 1989 season in order to attempt a comeback as a player. Alzado however did work Week 4's Chargers-Cardinals game alongside Jay Randolph. The announcerless and single-announcer games Don Ohlmeyer, then executive producer of NBC's telecasts of National Football League (NFL) games, began considering doing a telecast without announcers early in the 1980 season. He had several reasons. First, he had long believed that the announcers were overly chatty and did not let the game speak for itself when they needed to. Second, NBC, while it primarily covered the games of the NFL's American Football Conference (AFC) teams, generally in smaller
