The skinny on tuning in on broadcasting’s big day

Sunday’s Super Bowl between the 49ers and Chiefs marks the biggest day of sports broadcasting for networks.

Here are some things to know about Fox Sports’ coverage — which begins at 5:30 p.m. CT — as well as other Super Bowl-related programming on other networks.

9th Super Sunday for Fox: This marks the ninth Super Bowl broadcast for Fox and the second time it has done the game in Miami. CBS has done the most Super Bowls with 20, followed by NBC (19), Fox and ABC (seven).

In the booth: Joe Buck and Troy Aikman will call their sixth Super Bowl, the most by an announcer/analyst team on one network. Of the 22 pairings who have done the game on television, Pat Summerall and John Madden own the record with eight — five on CBS and three on Fox. Mike Pereira and Dean Blandino will be the rules analysts. Reporters Chris Myers (fifth Super Bowl) and Erin Andrews (third) will be on the sidelines.

Production notes: Fox will use more than 90 cameras for the game, including multiple 8K cameras. This will also be the first time that the entire game will be shot in 8K.

Ratings: The average audience for the playoffs is down 2% from last year. It was up through the first two rounds but took a dive because the championship games were not close. Last year, both went to overtime. How will that translate for the Super Bowl? Last year’s game on CBS between the Patriots and Rams averaged 98.19 million viewers, the lowest since 2008, when 97.45 million watched the Giants ruin the Patriots’ bid for a perfect season. The record is 114.4 million for the Super Bowl between the Seahawks and Patriots in 2015, which was on NBC.

Pregame coverage: Fox comes on the air at 10 a.m., with “Skip and Shannon: Undisputed Super Bowl Special.” NFL Films’ “Road to the Super Bowl” follows at 11 a.m. and “Fox Super Bowl Kickoff ” at noon. The “Fox Super Bowl Pregame Show” comes on at 1 p.m., leading into kickoff at 5:30 p.m.

Other pregame programming: NFL Network will air an 81⁄2-hour edition of “NFL GameDay Morning” starting at 8 a.m. ESPN’s “Postseason NFL Countdown” will go on the air at 9 a.m. for four hours. For those with pregame fatigue, the Puppy Bowl kicks off on Animal Planet at 2 p.m.

For the cord cutters: AT&T Now, Sling, Hulu, YouTube TV and fuboTV all have Fox. For those who don’t subscribe to a streaming service, it will be available on the NFL’s website.

Spanish broadcast: Fox Deportes has the Spanish-language broadcast for the third time. It will have eight hours of coverage beginning at 2 p.m.
