In the latest effort to keep Hulu content off TV sets and on computer monitors only, users of PlayStation 3 consoles, who have been using the device to bring online video to their TV sets, discovered on Monday that they were blocked from doing so with Hulu. Instead, according to Gizmodo.com, they received the message, "Unfortunately, this video is not available on your platform. We apologize for any inconvenience." In February Hulu blocked users of the Boxee platform -- which streams video to TV sets via other settop boxes like the AppleTV -- from accessing the site, saying it was doing so at the request of "our content providers." The principal content provider on Hulu is NBC Universal, whose CEO, Jeff Zucker commented that he had blocked Boxee because "we're committed to Hulu being an online experience."
