Sony trademarks social and multiplayer service BigFest
Sony Computer Entertainment Europe's London office, which produced PlayStation Home, has filed a trademark application for something called BigFest.
BigFest is trademarked for "hosting on-line web facilities for interactive game play; hosting web sites of others for video and computer games or parts of video and computer games created by others on a computer server for a global computer network” and “introduction and social networking services, namely, introducing video game players to each other for the purposes of playing multiplayer games online, participating in online games communities and competitions, and online player networking and social introduction".
It sounds suspiciously like Home, which now houses several multiplayer games, although it could have broader application.
A screencap of the full trademark listing is available on IGN.
