A podcast is like radio-on-demand. Instead of having to listing to your favourite shows when they broadcast, you can subscribe to them and listen when you have the time. This also means that you can catch up on missed shows.
Each Radio Lillooet show has its own blog where you can listen to its podcasts. You can find the Canadian Anna blog at this address: http://radiolillooet.ca/s/canadian-anna/.
But what is great about podcasts is that you can get a program to automatically download new episodes for you. If you already have iTunes or the Zune Player, then just click the link at the top of the page. If you have a different podcasting tool, then you should copy the RSS address and paste it into your tool.
