Podcast is one of those words whose meaning has changed quite a bit in the space of a few months. When I first defined it in January 2010, it was a not very sexy technical term that didn’t seem to invite much comment. The original definition of podcasting went like this: a combination of Ipod and broadcast, a way of broadcasting video or sound files online, hence podcasts. It allows you as a listener to come back to the file whenever you want: all you have to do is listen to it via your podcast player (like iTunes or AmaroK). As an example, you can listen again to a BBC radio programme by going to the BBC website, where the Podcast feature lets you download the programme on your computer to hear it (or listen to it again) whenever you want. The advent of the podcast has definitely brought greater freedom.
