a Podcast is an audio or video file you can down load from the net. You can then play this audio or video file on your Computer, MP3 Player or Smart Phone.
‘Podcast’ generally refers to audio. ‘Video Podcast’ (or ‘Vodcast’) refers to the distribution of video files in the same manner.
Pod-cast is a play on the word Broadcast combined with iPod. A podcast is a broadcast over the internet origanally coined for play back on an iPod. Unlike traditional ‘broadcasts’ a podcast is a file that can be stored and replayed over and over. Similarly, a series of podcasts can be listened to in any order or can be listened to from The beginning years later.
