or 2000. Called PocketDJ, it would have been launched as a service for the Personal Jukebox or a successor, the first hard-disk based MP3-player. In 2001, Applian Technologies of San Francisco introduced Replay Radio (later renamed into Replay AV), a TiVo-like recorder for Internet Radio Shows. Besides scheduling and recording audio, one of the features was a Direct Download link, which would scan a radio publisher's site for new files and copy them directly to a PC's hard disk. The first radio show to publish in this format was WebTalkGuys World Radio Show, produced by Rob and Dana Greenlee. Timeline In September 2000, the first system that enabled the selection, automatic downloading and storage of serial episodic audio content on PCs and portable devices was launched from early MP3 player manufacturer, i2Go. To supply content for its portable MP3 players, i2Go introduced a digital audio news and entertainment service called MyAudio2Go.com that enabled users to download episodic news, sports, entertainment, weather, and music in audio format for listening on a PC, the eGo portable audio player, or other MP3 players. The i2GoMediaManager and the eGo file transfer application could be programmed to automatically download the latest episodic content available from user selected content types to a PC or portable device as desired. The service lasted over a year, but succumbed when the i2Go company ran out of capital during the dot-com crash and folded. The RSS connection In October 2000, the concept of attaching sound and video files in RSS feeds was proposed in a draft by Tristan Louis. The idea was implemented by Dave Winer, a software developer and an author of the RSS format. Winer had received other customer requests for "audioblogging" features and had discussed the enclosure concept (also in October 2000) with Adam Curry, a user of Userland's Manila and Radio blogging and RSS aggregator software. Winer included the new functionality in RSS 0.92 by defining a new element called "enclosure", which would simply pass the address to a media aggregator. On January 11, 2001, Winer demonstrated the RSS enclosure feature by enclosing a Grateful Dead song in his Scripting News weblog. For its first two years, the enclosure element had relatively few users and many developers simply avoided using it. Winer's company incorporated both RSS-enclosure and feed-aggregator features in its weblogging product, Radio Userland, the program favored by Curry, audioblogger Harold Gilchrist and others. Since
