An interesting tangent. The term broadcast for radio comes from farming and broadcasting seeds when planting. Podcast naturally evolved from that term. I’m imagining the podcast they listened too is called “Peas In A Pod.” with talking peas discussing plant facts.
The Pod in podcast comes from Ipod, back in the olden days an Ipod was the only way to listen to Podcasts
It wasn’t technically the only way, but it was definitely one of the most popular ways
What other way was there?, directly fom the website, or with the zune (another ancient reference)
They were just mp3s from an rss feed, so you could listen on your computer as well, through your favorite music player (winamp!) or there were also dedicated podcast clients - Juice is one of the oldest, cross platform, open source ones I remember.
