PHILO Is Twitter + Foursquare For TV Fanatics. A new web and iPhone app [iTunes link] called PHILO makes watching TV interactive by having users "tune in" to TV programs as if they were checking in to venues on Foursquare or Gowalla, then discuss shows in a Twitter or Facebook newsfeed-like conversation stream while they're watching.
The app shows you what's trending among your friends, and you can use it as a discovery engine to find new shows. You can then determine when those shows are playing on your local cable or satellite TV provider. When you do have something to watch, your updates can optionally be broadcast to Facebook and Twitter so your friends can see what you're watching and what you think of it. Foursquare-like badges are on tap for users who check in to programs regularly.
