Mobile Tube. Sony Ericsson Germany is running a YouTube-based campaign for its W995 handset using interactive video. The clip features four navigation buttons. The ‘Video Quiz’ tab links the user to a contest featuring Jan Delay where players can win a W995. The ‘PlayNow Arena’ button delivers a showcase of all the content available for the phone. The ‘Top Features’ channel delivers… well, you kinda know already. While those clicking on ‘YouTube Function’ get to see how they can put the viral video site in their pockets: Nice use of i-video functions – expect more campaigns like this on YouTube, though perhaps more exciting.
