Vudu

Vudu, which is now owned by Wal-Mart, came out with its set-top box in early 2008. It did a handful of things, though its main purpose was to serve up streaming movie rentals. These could also be purchased, and stored on the device.

Along with the movie and TV show service, Vudu came out with an applications interface called Vudu Labs that has media exploring apps like Pandora, Flickr, Picasa, and YouTube. There's also an on-demand TV app that has 120 channels.
