Streaming the Super Bowl on Tub's free service at 4K quality could be great for fans. Or it could overwhelm systems, frustrating fans who just want to watch the Big Game.

Fox's Tubi will host two feeds as the reigning champion Kansas City Chiefs take on the Philadelphia Eagles on Sunday.

While Tubi’s pricing is far lower than the $7 million to $8 million advertisers paid for 30 seconds of national ad space on Fox, the audience will also be much smaller than broadcast’s, which last year hit 120 million on CBS out of the 123.4 million total for Super Bowl LVIII.
