3What is it?• Inspired by the iPod• Usually refers to any software and hardware combination enabling automatic download of audio files (most commonly in MP3 format) for listening at the user’s convenience• Makes use of the Internet’s Real Simple Syndication (RSS) feeds – Content is sent directly to an iPod or other MP3 player
