Even with the support, Apple will have little more than 75 movies available for download at first.
At the event, Jobs compared the launch of the movie service with the initiation last year of a related service that allows customers to download television shows. That service also began with the support of just Disney and only five shows.
Apple now offers 220 shows from all the major networks.
"We'll be adding more [movies] every week and every month," Jobs said.
Still, the lack of support from other studios at the launch of the movie service was a disappointment, especially given that

launched a rival service last week
with support from five of the top six movie companies. Amazon, it should be added, does not yet offer downloads of Disney movies.
Jobs also unveiled updates to each of the company's three lines of iPod music players. But the updates were relatively sedate compared with rumors that have been bandied about concerning what the company has in the works.
In other words, Apple didn't announce a new music-playing cell phone, didn't introduce a full-screen iPod and didn't introduce a model with built-in wireless networking.
Instead, the company increased the storage on some models, cut prices on some, added colored cases to its nano line and tweaked the iPod's underlying software.
