If you are a regular MSR reader you may remember that when the AT&T/DirecTV acquisition came to pass, we wondered how long it would take before AT&T and Verizon started battling each other in the quest to bring live NFL action to fans on their phones. The answer: wait no more, the battle’s here.

Today, AT&T announced that all subscribers to the DirecTV Sunday Ticket plan “will be able to stream Sunday afternoon out-of-market football games to almost any device” when action kicks off this fall. Previously, Sunday Ticket subscribers had to shell out about an extra hundred bucks to get the Sunday Ticket Max package, which offered streaming. Last year, the basic Sunday Ticket package was about $250; so far we can’t find a price for this season (and we don’t want to hunt through all the splash screens trying to get us to sign up for DirecTV services). Suffice to say it will still be a premium product, but one that many NFL fans can’t live without.

According to AT&T, live streaming via the Sunday Ticket plan was up 35 percent last year, a figure that doesn’t surprise us at all. We’ve been tracking Verizon Wireless and its NFL Mobile package of live-streamed games (which varies but usually includes Monday, Thursday and any weekend games, as well as Sunday out-of-market games) for some time now, and posts about NFL Mobile typically draw the highest traffic to our site. Verizon has never released subscriber numbers for NFL Mobile, but if you guessed it was among the most popular sports apps out there, you would probably be right. Even at $1 billion for four years, the rights fees seem a bargain for Verizon.

DirecTV pays the NFL more (about $1.5 billion a year, according to reports) but it gets more; NFL Mobile is exclusive to cell phone devices, meaning you can’t use it on tablets or PCs. And now thrown into the mobile mix is Twitter, whose reported $10 million deal with the NFL for Thursday-night games also includes the rights to stream to cell phones and any other device. Anyone else out there want to play?

Why is NFL action so popular on mobile devices? Mainly, I think, because of several factors, including fantasy betting and the fact that the screens have gotten so big and sharp, you can actually watch a game on a phone and it’s not painful. As many of us mobile-NFL freaks know, the best part of the deals isn’t necessarily the games themselves, but instead it’s access to the NFL’s RedZone channel, which keeps you up to date on action all across the league (and despite its name, it offers way more than just plays “in the red zone.” They try to keep live action going at all times, and NO COMMMERCIALS makes it a football junkie’s dream).

Plus, on the West coast, RedZone will often just show all of later games since there are fewer contests to jump in between. I don’t know how many people will sit every Sunday through several games on the couch, but if you can watch a few minutes or a final drive while you’re somewhere else it’s pretty addictive.

No news yet this year from Verizon on what the NFL Mobile package of games might look like, but stay tuned: This battle is just getting started. Good news is, more competition means more access and lower prices for fans. That’s something we can all cheer, no matter which teams we root for.
