Facebook's f8 developer conference is going on today, and Andy Samberg Mark Zuckerberg has just revealed another part of his master plan for the social network. Open Graph will now integrate many of your favorite news and music services, including Spotify, Rhapsody, Rdio and MOG onto your Facebook page with custom apps, and will also bring video from Vevo, Netflix, Hulu and many more. The media platform's already up and running, so you can see (and hear) the results of Mark's labor right now.

Update: Unfortunately for Facebook users in the US, Netflix has confirmed that its Facebook integration will only be available in Canada and Latin America initially, due to a US law that "creates some confusion over our ability to allow U.S. members to share what they watch." That doesn't apply to the music services, however, and you can get an idea how Spotify will work in the video after the break. Even TiVo's gotten in on the action, announcing new sharing buttons for its iPhone and iPad mobile apps, although there's no direct DVR integration mentioned yet.
