iTunes has released Star Wars "The Clone Wars" formatted for release on iTunes. The first series consists of 20 three-minute episodes.
It’s a great example of the right content for portable devices. I’ve been discussing with different companies providing video to mobile networks here in the UK what impact the iPod video, PSP, etc they expect to see on video sales/downloads to mobile phones. There are mixed opinions, but most believe that video downloads on mobile phones will be a long time coming.
I’m convinced that unless the consumer experience can equal that of iTunes, mobile video on phones will never really take off. If you have $10 to burn, I recommend you grab the Star Wars series and Channel Frederator (free) on iTunes.
