"Our next challenge is to broaden our content offerings, so that customers can enjoy watching more videos on their computers and new iPods," Jobs said.
Jobs has said that he expects exclusive content deals to be a key driver behind video downloads, another reason why the number of TV episodes sold would have been interesting, Chanko said.
"We should know whether the driver behind this one million number is 'Desperate Housewives,'" Chanko said. "Is there in fact a critical mass of downloads represented by 'Desperate Housewives?' If so, that would be interesting."
Apple's iPod is the most popular digital music player, accounting for about three quarters of the market. The company introduced the video iPod Oct. 12 at a news conference in San Jose, Calif. The largest 60 GB version can hold 15,000 songs, 25,000 photos or more than 150 hours of video, according to Apple.
