A webcast is similar in intent to a broadcast television program but designed for internet transmission. Webcast clients allow a user to connect to a server, which is distributing (webcasting) the webcast, and displays thetelevisual content to the user.

Initially webcasts were non interactive, in other words, the user was not able to alter the content of the webcast or to interact with the subjects of the webcast. For the most part they were also hosted live (with recordings retained for later dissemination), however more recently there has been greater overlap between video conferencing and webcasting such that webcasts have been generally consigned to being recordings of video conferences and training material where there is much less demand for an interactive session.
