DM110 Emerging Web Media Dr. John Breslin [email_address] http://sw.deri.org/~jbreslin/ Week 5: Audio Podcasting

Podcasts are like audio blogs “ Podcasts are to radio what blogs are to newspapers and magazines” The name “Podcast” is a portmanteau of “pod” from iPod and “broadcast” 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 Can be interviews, music shows, comedies, etc. Famous podcasters include Ricky Gervais for the Guardian Unlimited site

“ Podcasts are to radio what blogs are to newspapers and magazines”

The name “Podcast” is a portmanteau of “pod” from iPod and “broadcast”

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

Can be interviews, music shows, comedies, etc.

Famous podcasters include Ricky Gervais for the Guardian Unlimited site

What distinguishes a podcast from an MP3? Many sites offer downloads of audio files or streaming audio content (in MP3 or other format) But podcasts differ in that they can be downloaded automatically via a syndication process (“push technology”): When a new audio file is added to a podcast channel, the associated syndication feed (usually RSS or Atom) is updated 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 (More about content syndication later in this course…) Can be accompanied by show notes
