The iPod was discontinued in 2022. I'm guessing there's already a lot of kids who have no idea where the term "podcast" comes from.
The Famicom Disk System, which uses a kind of floppy disk for the Japanese market NES, had kiosks where you could copy games onto disks. The last of those kiosks were removed in 2003
It overlapped the Game Cube.
Apple didn't invent the concept of podcasts, but they sure popularized them. They used to be called syndicated audio, and were pretty niche. Then Apple added it as a feature of iTunes. The idea was that because your iPod didn't have any wifi or data connection, you couldn't listen to new content while out and about. So you would plug your iPod into your computer with iTunes to sync down all the latest content before you leave for the day. Then they needed feeds of new content to provide to the users, so lots of new episodicals were started, and Apple grouped them under the umbrella of "podcasts".
Apple never made a product called iTouch. You're thinking of a product called "iPod Touch". It was the touchscreen version of the iPod (without the iconic clickwheel). The first one was essentially a slimmer iPhone 3G without a cellular modem.
I worked in an electronics repair store just after they came out. We replaced hundreds of broken screens on them. The sheer number of people who called them "iTouch" was surprising, considering Apple never called it that.
