One of the biggest areas of TV that’s undergoing a social transformation is the program guide. Clicker.com is the latest to jump into the social sphere with a partnership with Facebook.

Much like RottenTomatoes.com does with movies, Clicker.com offers recommendations based off the TV shows you and your friends have “liked” via Facebook. The more you like — on Clicker.com or other Facebook-enabled sites — the better the recommendations.

Besides displaying what your friends have “liked,” Clicker.com also displays show trending with your friends (which is a little of everything right now, as people give it a spin.)

“When you find shows that interest you, click through to watch them on the websites that host the content,” including Netflix, Hulu, Amazon and iTunes, explains Facebook’s Matt Kelly. On show pages, like 30 Rock above, you can see the number of “free” (Hulu) and “paid” episodes (Netflix) available to watch — cool features for people like me who watch a ton of TV online.
