Facebook Catching MySpace in the U.S.

According to new data from Hitwise, MySpace rang up a stunning 73 percent of U.S. visitor market share for social networks in June, CNET News reports. However, that’s down by 6 percent compared with the same period last year. Meanwhile, Facebook captured about 17 percent of the U.S. market, which marks a big gain of 40 percent from the same period one year ago.

MySpace users still spend more time on the site than Facebook users on average—31 minutes versus 21 minutes—but again, the numbers in that category are getting closer as well. Both portals have robust mobile social networking options, from WAP portals and standalone applications, to specific carrier tie-ins with certain handsets.
