What is podcasting?
The concept of podcasting was suggested as early as 2000 and its technical components were available by 2001. In 2003 regular podcasts started showing up on well-known Web sites and software support spread.
Podcasting is like broadcasting in that someone creates a show for an audience. The difference is that broadcasting is done for a general audience to tune in (through television, radio, or Internet radio) while podcasting is much different, you can target a specific niche which makes the power of podcasting much more exciting.
Podcasting is an automatic mechanism whereby multimedia computer files are transferred from a server to a client, which pulls down XML files containing the Internet addresses of the media files. In general, these files contain audio or video, but also could be images, text, PDF, or any file type.Podcasting's initial appeal was to allow individuals to distribute their own "radio shows," but the system quickly became used in a wide variety of other ways, including distribution of school lessons, official and unofficial audio tours of museums, conference meeting alerts and updates, and by police departments to distribute public safety messages.
