Launched five years ago, GetGlue offers check-ins for all types of media including TV shows and movies. In recent months, the free service moved to a more TV Guide-like approach.
Viggle, meanwhile, launched earlier this year with a focus on loyalty engagement. As such, users get points for checking into TV shows. These points are then redeemable through sites such as iTunes and Amazon.
To date, GetGlue has 3.2 million registered users, while Viggle has 1.2 million users. As of now, both sites will remain separate, according to a press release.
