NBC has partnered with Motionbox to create four new groups on the video-sharing site - NBC4, NBC5, NBC10 and Football Frenzy. Even more importantly, NBC has integrated Motionbox's functionality into its own sites - users can upload videos, tag them and share them with others (example). Jumpcut did a similar deal with Fox Atomic back in July.
It's also worth noting that NBC are extremely active in this space - an NBC-YouTube deal was signed back in June to distribute the network's content through a branded channel, and the company has snapped up YouTube stars like Barats and Bareta. Others, like Brooke “Brookers” Brodack are promoting a new NBC video sharing site. It's a dramatic turn around since the Lazy Sunday controversy in February, when NBC pulled the popular clips from YouTube due to copyright infringement.
As mentioned previously, Motionbox recently announced funding, and launched new features like deep tagging and a player for MySpace.
