they've announced lionsgate.
But yeah, I just don't see apple getting big success in the the movie/tv buisness right now. First, as pointed out by others, you can't rent movies, and rentals make way more sense for movies. The pleasure with music often increases when you know it and you can sing along, but with movies, you usually don't care to watch it much when you know where it is going. Second, if I have a movie in mind that I want to see and I go to netflix, brick and mortar video store, whatever, I can expect to find it. Not on itunes. It sucks to shop somewhere when they don't have what you're looking for, even if you don't have to leave your house to do it, and if it happens too much, you'll stop trying. So not only does apple need a way, WAY bigger selection, they need to change their image with respect to that.
And the smaller pieces -- the devices, the popularity of digital video, the bargaining power, the appeal of the model to studios, are all worse than they were with music when the ipod was introduced.
So yes, adding these studios is helpful, but it seems to be baby steps towards being just OK, while the competition is plentiful and moving by leaps and bounds (like netflix's streaming option that is just revolutionary, and I think has a wider video selection at it's start than itunes has now, although I'm not sure since it's not mac compatible).
