"In researching the kickoff time shift, the NFL analyzed games from the 2009-11 seasons and found that 44 games required part of the audience to be switched to a mandatory doubleheader game kickoff," a release from the league reads. "With a 4:25 p.m. ET kickoff time, that number that would have been reduced by 66 percent to only 15 games"
Butchered, awesome Jerry Glanville quote aside, the NFL is probably the most fan-friendly, forward thinking professional sports league (at least when it comes to non-concussion-related topics). Sunday Ticket, NFL RedZone, and NFL.com give you almost anything you could possibly want to see on Sunday, if you're willing to pay a bit. If you don't want to pay, you still usually get at least three games on Sunday, and now, if the early game is close, you won't get yanked away before seeing the final plays of the game.
If the NFL would follow MLB and the NBA's lead and put out an app (at say $10-20 a season) that let you listen to the radio broadcasts of any game, it would probably make a gajillion dollars.
MLB, with its At Bat app and web service, Apple TV/Xbox Live integration, and really well done MLB.com and MiLB.com sites, would be a shoo-in for fan friendly behavior, but their continue adherence to their absurd YouTube and blackout policies mean that, no matter what they do, they're always going to be second place.
