Podcasting is a method of publishing audio and video programs via the Internet that lets users subscribe to a feed of new files.

You don't need an iPod to listen to a podcast. Any MP3 player or computer will suffice.

A survey of 470 high school students found that 61 percent of students had some kind of MP3 player.
