Fox and ABC) have dipped a toe in with specialized iPad companion apps, NBC is going a different route with the recently launched NBC Live. From the screens, it's able to pull up information on multiple shows in a similar style to the website and provides social feeds and interactive features between viewers while they watch the show on TV. What it doesn't do is stream video to the iPad like the ABC Player has since launch which, judging from some of the reviews, is confusing to would-be users. It's a free download though, so try it out and let us know if you're interested in "tuning in, interacting and engaging" with Parks & Rec or 30 Rock in a whole new way.
