verb. To record (usually spoken narrative) audio files (usually in MP3 format) and make them available on-line so that they can be downloaded and listened to rather like an ‘on-demand’ radio show.
Although podcasts can be listened to on any suitable hardware (i.e. a computer or MP3 player), the term ‘podcast’ derives its name from the iPod, a very popular portable MP3 player made by Apple.
