Podcasting has become a common term nowadays, though there is actually only a selected number of people who are aware of its sense and function. The meaning of podcast is still unknown to a large number of people. The word –podcast, has been coined by juxtaposing broadcast and ipod.These specially designed broadcasts were initially formed exclusively for the ipod. However, later they were made accessible for people who did not own an ipod because of the increasing fame of the podcasts. Thus, an ipod is not essential anymore to know about a podcast- you can hear it on your computer or in your music player.Podcasting is a method by which media files such as audio or video are advertised and circulated over the internet.
