Podcasts! Another new buzzword. Apple computers' Steve Jobs called it "Waynes world for radio" but acknowledged it's importance by including the ability to find & download them from within Apples i-Tunes software.
Let's clear up what podcasts are. They are audio files, out there on the internet, ready to download & listen at a time of your choosing either on your computer, on your mp3 player or burnt to CD & listened to on your portable CD player. originally podcasts were just ordinary people talking about things that interested them & indeed that still exists. It didn't take long for radio & record companies to catch on to the promotional aspect of this new medium & so we now find that the majority of content probably comes from radio around the world.
If you don't have i-Tunes (Mac or PC) then one place you might start looking for podcasts that might appeal is at podcastalley.com.
So, the world of timeshifted radio is here. Like having a video recorder for radio.
