What is webcast?

    According to Wikipedia “webcast is a media file distributed over the Internet using streaming media technology. A webcast may either be distributed live or on demand. Essentially, webcasting is “broadcasting” over the Internet.”
    A webcast uses streaming media technology to take a single content source and distribute it to many simultaneous listeners/viewers.
    The term webcasting is usually reserved for referring to non-interactive linear streams or events. Webcasting is also used extensively in the commercial sector for investor relations presentations (such as Annual General Meetings), in E-learning (to transmit seminars), and for related communications activities. However, webcasting does not bear much, if any, relationship to the idea of web conferencing which is designed for many-to-many interaction.

    According to PCMAG Webcast means to:
(1) To send live audio or video programming over the Web. It is the Internet counterpart to traditional radio and TV broadcasting.
(2) To send selected Web-based information (text, graphics, audio, video, etc.) to Internet users based on individual requirements. See push technology.

    According to webopedia Webcast means: To use the Internet to broadcast live or delayed audio and/or video transmissions, much like traditional television and radio broadcasts. For example, a university may offer on-line courses in which the instructor Webcasts a pre-recorded or live lecture, or an enterprise may Webcast a press conference in lieu of or in addition to a conference call. Users typically must have the appropriate multimedia application in order to view a Webcast. www.webopedia.com
