"Fox Corp. is willing to spend as much as $2 billion a year to maintain its rights to National Football League games on Sundays, a huge increase from its current contract, according to people familiar with the matter," Bloomberg News reports. "Under the existing arrangement, the network airs games from the National Football Conference, featuring teams from the big media markets of New York, Chicago and Los Angeles. That makes it the most-coveted outlet for advertisers. Now Fox has to fend off other broadcasters, which also want to air high-profile matchups." The NFL's current broadcast rights expire at the end of next season.
