The online hangout MySpace got even more popular in November, beating Yahoo in Web traffic for the first time, a research company said Tuesday. News Corp.’s MySpace recorded 38.7 billion U.S. page views last month, compared with 38.1 billion for Yahoo, according to comScore Media Metrix. MySpace’s growth was 2 percent over October and triple the 12.5 billion recorded in November 2005. The numbers underscore the rapid rise of a social-networking site that encourages visitors to stay and make friends through free tools for messaging, sharing photos and creating personal pages known as profiles.
