Podcast

noun; compounding
Non-profit audio or video recordings, broadcast on the internet, that can be played on computers and portable digital audio players, such as iPods. The podcast is a new concept that has become very popular over the internet. A podcast may be about any subject conceivable by the podcaster. They are often in the format of radio programs, and some traditional radio programs are distributed by podcasting. The free nature of podcasting, which can be done by anyone, anywhere with a computer and a microphone, makes it a very dynamic medium. As the practice of podcasting evolves, its name will also evolve to mean different things. The word “podcast” seems to imply that they can only be played on iPods, when they are mostly in .mp3 format that can be played in any computer or digital music player. This shows the generalization of “iPod” to include all other mp3 players. Interestingly, trendsetters are called their iPods “mp3s”, as iPod are so popular that they have become commonplace. In the quotation, podcast is an adjective. This is a zero-derivation from the noun form, which was the name originally given to the practice. There is also a verb form for the process of broadcasting a podcast. The software used to subscribe to podcasts is called podcatching software. Here, podcasting is clipped to pod and compounded with catching to form this new word.
 
Steve Jobs recently demonstrated a similar feature and announced that some podcast features will be offered in the next release of iTunes later this year.
