MySpace is now the number one site in the U.S. in terms of market share of visits says research firm Hitwise. Over the past two weeks Murdoch’s social network grew in market share of visits to reach 4.46% for all Internet visits in the U.S. for the week ending July 8th. The Hitwise stat launches MySpace over Yahoo Mail for the first time. Of course that’s good news for the site’s plans to build a socially integrated media empire.
For the entire month of June, ComScore’s data still places Yahoo over MySpace in terms of visitors, but said that MySpace still grew in both page views and unique visitors. We’ll see when next month’s numbers emerge if the trend stays the same. When it comes to unique visitors, though, MySpace isn’t growing as fast as Yahoo, Time Warner Network, MSN-Microsoft, Google, or eBay–it’s ranked 6th on uniques.
