A bit of history
I listen to a lot of podcasts. I spend more time listening than I do reading, and I have several months worth of non-stop listening downloaded, waiting to be heard.
I first listened to podcasts in the late ’90s, before they were called podcasts, and before there were iPods. I’d been on a business trip to the US, and left my card in a prize draw. Some time later at work I received a notice that I had something to pick up from customs, and had to pay import duty. I left it a few weeks, as I didn’t know what it was. It turned out I’d won the draw, and it was a Diamond Rio PMP300 mp3 player.
Once I understood what it was for, I couldn’t get enough of it. In those days ‘mp3’ was nearly always described as a ‘music format’ rather than an audio format, and there were very few podcasts of interest or quality, but there were a few.
The iPod was released in 2001, and ever so slowly the world of ‘podcasts’ came about. For a while, I just found it annoying that these downloadable radio shows were considered as something new, and, seemingly, something that Apple had invented. But I got over it.
Most of the descriptions below are from the podcast websites.
