In addition to announcing a transition to Intel processors for Macs, Apple CEO Steve Jobs offered an update on iPod and iTunes sales, as well as a look at the upcoming podcast support in iTunes during his keynote speech at Apple’s Worldwide Developer’s Conference in San Francisco.

Jobs said that 16 million iPods have been sold as of the end of March, accounting for 76% market share of all music players. He said more than 430 million songs have been purchased and downloaded from the iTunes Music Store so far, and that it commands 82% of legal digital music sales.
The Apple chief next discussed the previously announced podcasting features of iTunes 4.9. Jobs called podcasting “iPod plus broadcasting,” “TiVo for radio” and “Wayne’s World for Radio.” He said that anyone can make it and get a worldwide audience, and said Apple sees it as the hottest thing going in radio right now.
Jobs said you can easily subscribe to the podcasts and have them automatically synced to your iPod. “We’re going to make this even easier,” he said. “We’re going to build it right into iTunes and iPod.” Jobs then went into a quick demo in which podcasts were shown in the source list of iTunes, and there was a podcast directory directly in the application. He quickly went to Adam Curry’s “The Daily Source Code” and then to KCRW public radio. Subscribing was as easy as clicking one button.
Finally, Jobs said that Apple plans to do its own podcast for iTunes Music Store releases every Tuesday, and revealed that artwork will be supported for each podcast.
