A podcast is a show that you download from the internet and listen to whenever you want. It’s like getting a radio broadcast in a doggy bag. It has nothing to do with seedpods and everything to do with iPods.
Podcasts are a lot like radio programs, except you can subscribe to a podcast, download it, and play it on a digital device, like a smartphone or a computer. It’s also very DIY friendly — you could podcast the funny conversations you and your friends have about movies, or a radio play put on at a local elementary school. The word podcast first appeared in 2004, from iPod and broadcast.
