Bebo, the San Francisco-based social network that's more popular overseas, launched a platform called Open Media today. It allows content owners to publish videos on the site using their own formats and ads. Launch partners include CBS, MTV, ESPN and BBC. Content owner keep all the ad revenue. Users can become "fans" of these content owners, just like they can "fan" brands, bands and celebrities on Facebook. Impressive, but Bebo hasn't fully caught up to Zuckerberg & Co. until it's also illegally forcing users to endorse products.
