• 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
