  2. 2. Podcasts are like audio blogs <ul><li>“ Podcasts are to radio what blogs are to newspapers and magazines” </li></ul><ul><li>The name “Podcast” is a portmanteau of “pod” from iPod and “broadcast” </li></ul><ul><li>Basically, podcasts are MP3 audio files created by individuals or organisations, published on the Web and downloaded by others to their iPods or other MP3 playing devices </li></ul><ul><li>Can be interviews, music shows, comedies, etc. </li></ul><ul><li>Famous podcasters include Ricky Gervais for the Guardian Unlimited site </li></ul>
  3. 3. What distinguishes a podcast from an MP3? <ul><li>Many sites offer downloads of audio files or streaming audio content (in MP3 or other format) </li></ul><ul><li>But podcasts differ in that they can be downloaded automatically via a syndication process (“push technology”): </li></ul><ul><ul><li>When a new audio file is added to a podcast channel, the associated syndication feed (usually RSS or Atom) is updated </li></ul></ul><ul><ul><li>The consumer’s podcasting application (e.g. iTunes) will periodically check for new audio files in the channels that a consumer is subscribed to, and will automatically download them </li></ul></ul><ul><ul><li>(More about content syndication later in this course…) </li></ul></ul><ul><li>Can be accompanied by show notes </li></ul>
