Anyone can create a podcast, and too many people do. Like Webblogs, podcasts can be about everything and nothing. Favorite topics include pop music, computing, how great podcasting is, and, like, stuff.
Fortunately, many public and private radio stations make all or parts of their programs available as podcasts so that we can survive those cultural droughts that are known as pledge drives.
Language learners may be able to find short, simple podcasts about subjects they know something about (e.g., reviews of current movies) to practice with.

The iTunes podcast category called Public Radio includes many foreign-language programs.
Vodcasts, vidcasts, videocasts are a bit older than podcasts, and they can be played on your browser and on some players. iTunes and Google offer selections of free and for-sale videos.
Podcasts aren't the only Webcasts you can listen to or watch. Many sites offer streaming audio or video of current and recent productions. Audio software like RealAudio or Windows Media Player are used to listen to or watch streaming. Podcasts are downloaded and may be kept, streams begin immediately and can only be listened to at that time.
