Video Podcasting
Podcasting is a web-based form of broadcasting. Podcasting allows users to watch and listen to exactly what they want, when they want, and where they want. The most definitive and widely used definition of podcasting can be found in Wikipedia:
Podcasting is the method of distributing multimedia files, such as audio or video programmes, over the Internet using syndication feeds, for playback on mobile devices and personal computers. The term, coined in 2004, combines "iPod", the Apple portable audio or video device, and "broadcasting."
Whilst a lot of websites offer direct download or streaming of their content, a podcast is distinguished from other formats by its ability to be downloaded automatically using software capable of reading feeds like RSS.
Usually a podcast features one type of 'show', with new episodes released either sporadically or at planned intervals such as daily or weekly. In addition, there are podcast networks that feature multiple shows on the same feed.
