[bbc] Mobile TV has so far failed to deliver on its promise of ubiquity, but analysts expect worldwide user numbers to increase to 54 million in 2009.
Analysts also predict that by 2013 there will be about 300 million people watching analogue TV on the so-called third screen, their smart phone.
Industry watchers said the biggest potential will be in emerging markets.
"Mobile TV is just not as big a deal as we all thought it would be," Frank Dickson of Reed Business told the BBC.
"The idea combines the two biggest things around: TV and phones. Everyone has a TV and everyone has a mobile phone. So of course the industry thought the prospect of bringing the two together was going to be huge.
"In reality, live mobile TV has been very slow to take off," explained Mr Dickson.
