What is Podcast????

After we are so excited about PgMug Podcast, how many people really know what is podcast??

Podcasting is a method of publishing audio programs via the Internet, allowing users to subscribe to a feed of new files.

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.

Listeners may subscribe to feeds using "podcatching" software (a type of aggregator like iTunes), which periodically checks for and downloads new content automatically. Most podcatching software enables the user to copy podcasts to portable music players. Any digital audio player or computer with audio-playing software can play podcasts.

From the earliest RSS-enclosure tests, feeds have been used to deliver audio files as well as video.

"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 player. Aware of that misleading association from the beginning, some writers have suggested alternative names or reinterpretations of the letters "p-o-d", without winning much of a following. Another little-used alternative is "blogcasting", which implies content based on, or similar in format to, blogs.
