After search Google's youtube dominates video sharing market

YouTube (GOOG) now accounts 73% of all visits to video sites, according to the firm, which released its March numbers. That's a 32% increase from March 2007, and appears to have come largely at the expense other generic video sites such as MySpace TV (down 48%), Google video (down 52%) and Yahoo Video (down 18%).

The Hitwise numbers second Nielsen Netratings' latest data, which shows YouTube at 71.3 million unique visitors in March, or a little more than 70% of the 100.7 million visits to "video/movie" sites as defined by the research firm. In terms of total videos served, YouTube's share is more modest: just 48.5% of all video served on the Web, according to Nielsen's VideoCensus.
