first true podcast. Lydon's blog eventually became Radio Open Source; its accompanying podcast, titled Open Source (not to be confused with Adam Curry's Daily Source Code, which was also one of the first podcasts), is now the oldest still-running podcast. BloggerCon October 2003, Winer and friends organized the first BloggerCon weblogger conference at Berkman Center. CDs of Lydon's interviews were distributed as an example of the high-quality MP3 content enclosures could deliver; Bob Doyle demonstrated the portable studio he helped Lydon develop; Harold Gilchrist presented a history of audioblogging, including Curry's early role, and Kevin Marks demonstrated a script to download RSS enclosures and pass them to iTunes for transfer to an iPod. Curry and Marks discussed collaborating. Pushing audio to a device After the conference, Curry offered his blog readers an RSS-to-iPod script (iPodder) that moved MP3 files from Userland Radio to iTunes, and encouraged other developers to build on the idea. In November 2003, the company AudioFeast (later renamed PodBridge, then VoloMedia) filed a patent application for "Method for Providing Episodic Media" with the USPTO based on its work in developing the AudioFeast service launched in September 2004. Although AudioFeast did not refer to itself as a podcasting service and was not built on RSS, it provided a way of downloading episodic audio content through desktop software and portable devices, with a system similar to the MyAudio2Go.com service four years before it. (AudioFeast shut down its service in July 2005 due to the unwillingness of its free customers to pay for its $49.95 paid annual subscription service, and a lack of a strong competitive differentiation in the market with the emergence of free RSS podcatchers.) In May 2004, Eric Rice, then of SlackStreet.com, along with Randy Dryburgh of VocalSpace.com launched Audioblog.com as the first commercial podcasting hosting service. Audioblog.com became Hipcast.com in June 2006 and has hosted hundreds of thousands of podcasts since. In September 2004, the media-in-newsfeed idea was picked up by multiple developer groups. While many of the early efforts remained command-line based, the very first podcasting client with a graphic user interface was iPodderX (later called Transistr after a trademark dispute with Apple), developed by August Trometer and Ray Slakinski. It was released first for the Mac, then for the PC. Shortly thereafter, another group (iSpider) rebranded their software as iPodder and released it under that name as Free Software (under GPL). The project was
