You Third Screen? Is that the future for You Tube? According to AP that’s exactly what YouTube’s co-founder Steve Chen may have in mind. Bringing the video-sharing site to the mobile platform by next year could be the next frontier for the company, but what this means for the YouTube service already offered by mobile carriers such as Verizon and Vodafone is a lot less clear. Perhaps Chen sees the benefit of the rising youth market, which we reported about yesterday. And let’s not forget about the vast international markets, where computer ownership isn’t quite so common but everyone has a mobile phone. Finally these people will be able to see home-made videos and sitcoms from the 1970s!
