What is a Podcast?
Podcasting is a method of publishing audio broadcasts via the Internet, allowing users to subscribe to a feed of new files (usually MP3s). It became popular in late 2004, largely due to automatic downloading of audio onto portable players or personal computers.
Podcasting is distinct from other types of online media delivery because of its subscription model, which uses a feed (such as RSS or Atom) to deliver an enclosed file. Podcasting enables independent producers to create self-published, syndicated "radio shows," and gives broadcast radio programs a new distribution method. Listeners may subscribe to feeds using "podcatching" software (a type of aggregator), which periodically checks for and downloads new content automatically. Some podcatching software is also able to synchronise (copy) podcasts to portable music players. Any digital audio player or computer with audio-playing software can play podcasts. By 2005 some aggregators could play video as well as audio. With increasingly robust personal digital devices, such as Sony's PSP, podcasting is likely to continue to evolve.
"Podcasting" is a portmanteau word that combines the words "broadcasting" and "iPod." The term can be misleading since neither podcasting nor listening to podcasts requires an iPod or any portable music player. A little-used alternate is "blogcasting", although this usually only refers to recordings that are based on, or similar in format to, blogs.
