Podcasting is the method of distributing multimedia files, such
as audio programs or music videos, over the Internet using either
the RSS or Atom syndication formats, for playback on mobile devices
and personal computers. The term podcast, like 'radio', can mean
both the content and the method of delivery. The host or author
of a podcast is often called a podcaster. Podcasters' web sites
may also offer direct download or streaming of their files; a podcast
however is distinguished by its ability to be downloaded automatically
using software capable of reading RSS or Atom feeds.
Usually a podcast features one type of 'show', with new episodes
released either sporadically or at planned intervals such as daily
or weekly. In addition, there are podcast networks that feature
multiple shows on the same feed.
Podcasting's essence is about creating content (audio or video)
for an audience that wants to listen or watch when they want, where
they want, and how they want..
