Apple has announced that it is “taking Podcasting mainstream” by building everything users need to discover, subscribe, manage and listen to Podcasts right into iTunes 4.9, the latest version of its digital music software and online music store. iTunes users can now easily subscribe to over 3,000 free Podcasts and have each new episode automatically delivered to their computer and iPod.

“Apple is taking Podcasting mainstream by building it right into iTunes,” said Steve Jobs, Apple’s CEO. “Podcasting is the next generation of radio, and users can now subscribe to over 3,000 free Podcasts and have each new episode automatically delivered over the Internet to their computer and iPod.”

The new Podcast Directory in iTunes 4.9 features over 3,000 free audio programs, making it one of the largest Podcast directories in the world, with favorites such as ABC News, Adam Curry, BBC, Clear Channel, The Dawn and Drew Show, Disney, Engadget, ESPN, Newsweek and NPR member stations such as KCRW in Los Angeles and WGBH in Boston.

iTunes enables anyone to quickly and easily find and subscribe to their favorite Podcasts so that every time there’s a new episode, it’s automatically downloaded to their Mac or PC and Auto-Synced to their iPod. iTunes also makes it easy to manage multiple Podcast subscriptions with simple organization and display by episode and date. Starting today, iPods will offer an easy to use Podcast menu, including bookmarking within a Podcast and the ability to display color Podcast artwork.

iPod and iTunes are leading the digital music revolution. With over 15 million iPods sold as of March 31, the iPod is the world’s most popular digital music player, and the iTunes Music Store is the number one online music store with over 430 million songs purchased and downloaded worldwide.
