Podcasts are recorded audio files. They can be downloaded and played through various mobile applications, streamed online, or embedded in webpages. Podcasting is a form of Internet broadcasting that has taken off in the last decade with the rise of smartphones and portable audio players like iPods, Zune, or PDA’s.
Podcasts are the digital equivalent of the radio shows that people used to listen to on their way to work, but they’re usually more conversational and informal than traditional radio broadcasts. It seems like podcasts are everywhere these days–in newspapers like The Guardian, on TV programs like The Colbert Report, even in video games like World of Warcraft.
