If you didn't think the National Football League was really serious about its new digital network, think again. A mere week after arriving on the Apple TV, NFL Now is adding Yahoo Screen to the growing list of platforms it is currently available in. While the experience on Yahoo's internet video service won't be as fully fleshed as on Apple's streaming box or the NFL's own apps, it still gives football fans another way to keep up with their favorite teams and players -- after all, NFL Now is all about personalization. Yahoo says NFL Now content is limited to Yahoo Sports on the web and the Screen iOS app, but that integration with its Android equivalent is "coming soon."
