Will Mobile TV work?

Will people actually watch TV programs on their mobile phones with smaller screens?

Are people willing to pay for mobile TV channels? Isn’t Internet streaming such as Youtube or Ustream enough for mobile video service?

How will mmbi work on challenges that previous mobile TV projects had faced?
