As great as the streaming TV era may be, it frequently lacks the immediacy of conventional broadcasts. You can't always flip to your favorite network and start watching right away like you can with cable or satellite. ESPN, however, wants to recreate some of that experience. It just released a revamped Apple TV app whose centerpiece is automatic live streaming. If you've authenticated with a TV provider, the app will start playing a channel as soon as you hop in. This won't help much if it's playing the wrong channel, of course, but it could make the difference between catching a big play live and having to visit the on-demand video. Thankfully, that last part should also be easier.
