Brad Greenspan, calling himself “the founder” of popular social networking company MySpace even though the company disputes that he was, has acquired a majority stake in Flurl.com, a video search website that indexes over 1000 online video sites.

This is one of the first major investments by LiveUniverse, which Greenspan established to focus on video, entertainment and social networking companies. LiveUniverse said it will begin talks with potential strategic, financial, and content partners. LiveUniverse, which is different from Greenspan’s other investment firm, BroadWebAsia, has also invested in video site Vidilife.

Greenspan has been in legal standoff with MySpace.

Flurl.com, the leading independent video search engine, hit over 5.6 million unique users in September 2006, according to Comscore World data.
