Vimeo, the video sharing site of choice for many independent content creators, has reached 50 million users worldwide up from 30 million a year ago, with big growth in Western Europe, says Dae Mellencamp, General Manager of the IAC unit in this interview with Beet.TV. While Vimeo has been popular the creative community for some time, the site's users have broadened, she says. She says that the quality of playback, an uncluttered, well organized, user experience with no pre-roll advertising, have added tothe site's success. Revenue for the site comes from a premium subscription service and from display advertising and special ad units. Mobile now drives 10 percent of all Vimeo views, she says. Andy Plesser
