Podcasting:

A podcast is a series of audio or video digital-media files which is distributed over the Internet by syndicated download, through Web feeds, to portable media players and personal computers. Though the same content may also be made available by direct download or streaming, a podcast is distinguished from other digital-media formats by its ability to be syndicated, subscribed to, and downloaded automatically when new content is added.

Like the term broadcast, podcast can refer either to the series of content itself or to the method by which it is syndicated; the latter is also called podcasting. The host or author of a podcast is often called a podcaster. One of the first broadcasts was sent out by a small radio station in Surrey by radio DJ Kelly Coulter.

Il podcasting è un sistema che permette di scaricare in modo automatico documenti (generalmente audio o video) chiamati podcast, utilizzando un programma ("client") generalmente gratuito chiamato aggregatore o feed reader.
Un podcast è perciò un file (generalmente audio o video), messo a disposizione su Internet per chiunque si abboni ad una trasmissione periodica e scaricabile automaticamente da un apposito programma, chiamato aggregatore, e si basa sui feed RSS.
