Definition of podcasting
  Podcasting is a term used to describe a
   collection of technologies for automatically
   distributing audio programs over the
   Internet using a publisher/subscriber
   model. It differs from earlier online
   delivery of audio because it automatically
   transfers the digital media files to the
   user’s computer for later use.

Podcasting
  “Podcasting” combines two words: “iPod”
   and “broadcasting”.
  You don’t need an iPod to listen to a
   podcast! Any PC will be fine!
  Alternative terms would be “audio blog” or
   “audioblogging”
  “Personal On-Demand” & broadcasting,
   giving: POD-casting
Podcasting - What It Is
  A podcast is really just an mp3 audio file
   that is distributed via an RSS feed
   (typically by linking the mp3 file to a blog
   posting).
  Current “podcatching” software, such as
   iTunes and Juice (formerly iPodder), allows
   the user to subscribe to an RSS feed; the
   software will automatically download new
   podcasts when they become available.
Podcasting – The Author
  Create an mp3 file and put on the web
  Link to the mp3 file in a blog posting
Podcasting – The Listener
  Subscribes to the RSS feed for the blog
   using “podcatching” software (such as
   iTunes)
  New podcasts are automatically
   downloaded to the user’s PC – and can be
   played on the computer
  The mp3 files can be “synched” to a
   portable mp3 player, such as an iPod, for
   anytime, anyplace listening – mobile
   learning – “m-learning”.

  Jon Udell has identified the major factors
   behind the explosive growth of podcasting:
    Internet activity is pervasive.
    Broadband has grown very rapidly.
    The multimedia personal computer can “more or
     less be taken for granted.”
    The iPod phenomenon and “the rapid adoption of
     portable mp3 playback devices”.
    Creative Commons licensing permits the
     distribution of copyrighted content.
