The ad-supported video on demand (AVOD) space just got a little more crowded. Amazon subsidiary IMDb has launched a new free streaming service called Freedive. This is the same free service that we heard rumors about back in August. Freedive was expected to be an answer of sorts to Roku's Roku Channel, which offers free content to Roku users. That seems to be at least partially the case: the IMDb Freedive app is available on Amazon's Fire TV platform and not on competitors like Roku. Freedive is not just available on Fire TV devices — you can watch it in your browser right now, and Gizmodo is reporting that mobile apps are on the way. But you will have to log in with an Amazon account or IMDb account to watch. At launch, the selection is pretty solid for an AVOD service. Top titles include the movies Drive, Drunken Master, A Few Good Men, Foxcatcher, Memento, Monster, and The Patriot, plus the TV shows The Bachelor, Dallas, Gilligan's Island, Heroes, and Quantum Leap.
