What is Webcast?

The term "Webcasting" is used to describe the ability to use the Web to deliver live or delayed versions of sound or video broadcasts. NetTalk Live! is an example of the former. CNet and some other Web sites use the term "Webcast" to describe delayed or preview versions of movies, music videos, or regular radio and television broadcasts as a way to promote the live broadcasts. Each sample is known as a Webisode. Viewing Webcasts requires having an appropriate video viewing application such as the NetShow, RealVideo, or VXtreme streaming video players; these can usually be downloaded from any site offering a Webcast.
