Mobile TV
Wow - according to this interview with a guy at Nokia who's probably spent waaay more time thinking about TV content than I have, what people really want on their mobiles are not designed-for-mobile bits of video, but full broadcast stuff - what they see on their TV day-to-day.
That goes completely against what I've been anticipating, and whilst I'm suspicious that his view may be focus group-driven (asking people what they want, not watching them to find out)... he's seen the research and I haven't. Related Forum Nokia info lives here.
