A podcast is a media file that is distributed by subscription (paid or unpaid) over the Internet using syndication feeds, for playback on mobile devices and personal computers. Like ‘radio’, it can mean both the content and the method of syndication. The latter may also be termed podcasting. The host or author of a podcast is often called a podcaster.
Though podcasters’ web sites may also offer direct download or streaming of their content, a podcast is distinguished from other digital audio formats by its ability to be downloaded automatically, using software capable of reading feed formats such as RSS or Atom.
A podcast is typically an audio or video file which someone creates and uploads to the internet. What makes a podcast special is that people can subscribe to the podcast and then have new “episodes” downloaded automatically to their personal computers or mobile devices. Podcasts are a great way to provide “on-the-go” digital media. Students can download an audio recording of a lecture or a review video and then watch it on their mobile devices while walking between classes, riding the subway, or even doing household chores.
