The word “podcasting” derived from the combination of the words “iPod” and “broadcasting”. iPod, as you might already know, is a portable audio player produced by Apple Inc. Apple first coined the word “podcast” for portable audio files that could be played through their iPods. The word podcasting has been stuck since then. A podcast is simply an audio file that you can listen to on your music device. Originally podcasting was intended only for Apple iPods. But today, you can listen to podcasts on your computer with some music software such as Windows built-in Media Player or iTunes for mac (which has a podcast library), or your smartphone, or even in your car. It really doesn’t matter, as long as you have some way to play music on your device, you will be able to listen to podcasts.
