A podcast is like a radio station that only plays the topics that interest you.

I tried explaining what a podcast is to my Mum and the simplest explanation was – internet radio. With that description, although not entirely accurate, she understood.

Podcasts are totally free and once you choose to subscribe, they are downloaded automatically to your mp3 player whenever a new episode is released. Your mp3 player can be your phone (that’s how I listen to them), your iPad, computer, laptop or iPod – basically, any device that can play downloaded music will play a podcast.

Apple iTunes have a great page if you'd like more detail about podcasts, you can find it here.
