If a company is in the video business, and it is not Google (GOOG) YouTube, it might as well shut down. According to new numbers from HitWise YouTube had over 75% of the US visits to video sites in May. That was up 26% from the same month a year ago.

News Corp’s (NWS) MySpace had a share of 9%, down a shocking 44% from May 2007. The social network’s visitors clearly do not want to watch clips. No TV ad revenue for MySpace.

Yahoo! (YHOO) Video’s market share was down 31% to under 2% of the US pie.

Everyone else in the market was from hunger.
