Conventional wisdom still says that sports are the key to cable: people will stream their comedies and dramas, but will pay for their sports coverage, because Americans sure love their sports. So it is unsurprising, then, that over-the-top cable-alternative streaming services are lining up to add more sports channels to their programming, including PlayStation Vue.

Sony announced this week that its streaming-TV service, PlayStation Vue, is getting two new networks: NFL RedZone and the NFL Network, which should make devoted football fans happy.

The NFL Network airs Thursday Night Football games, and both networks run constant football-related prgramming, including commentary shows, clips, and highlights. Vue subscribers who take the NFL channels will also be able to log in and watch the channels through the website, any smart TV, and their mobile devices.

Vue already includes NBC, Fox, and ESPN streams, as well as CBS in some markets, on the lowest-available service tier — so it’s not a bad choice for football fans who want to part ways with their cable or satellite provider.

No word yet on what service tiers the NFL networks will be included with, or if they come with any extra cost. For that matter, Sony also didn’t specify when the launch is, other than “soon.” Presumably, however, it will be timed to the NFL preseason kicking off, and this year’s first exhibition game is on August 13.
