BARBARA ORTUTAYNEW YORK (AP) â¿¿ "Who am I to say I want you back? When you were never mine to give away." Those are the opening lines of a song that accompanies a "New Myspace" promotional video. The once-mighty social network is trying to stage yet another comeback with the help of Justin Timberlake. The new site, for which people can request an invitation, looks a bit like an entertainment-focused version of Pinterest, with a dash of Twitter and Facebook thrown in. But Myspace has tried redesigns before, to no avail. Will it work this time? "If you break my heart a second time, I might never be the same," continues the song, "Heartbeat," by the group JJAMZ. From the sound if it, Myspace wants to win the hearts and minds of tech-savvy hipsters. Founded in 2003 and initially a fast-rising star, Myspace attracted mostly teenagers and twentysomethings, offering them a place to express themselves online. It peaked in 2008 with some 76 million U.S. visitors in October. The site lost its footing as the fun of customizing profile pages began to bore its users and the site's heavy use of banner advertisements slowed the speed at which pages loaded. At the same time, people were already migrating to Facebook, which counted users 35 and older among its fastest-growing demographic. The company's new promotional video offers a 2-minute and 18-second peek into a slick, image-heavy site. The site's much cleaner look is a stark contrast to the old Myspace, which users often derided as messy and cluttered. Posted this week, the video promises that Myspace will start "totally from scratch," as if trying to shed its former self. It doesn't say when the new site will launch, only that it's "not ready quite yet." The new Myspace will let users connect to the site with their Twitter or Facebook accounts, a sign that it won't be competing with those sites as a social networking service. Rather, Myspace will continue with its entertainment focus, as a place to play and discover music, add photos, videos and playlists and connect with artists.
