BlogTalkRadio is Internet radio that allows users to host live call-in broadcasts using only a computer and a phone.
BlogTalkRadio is entirely Web-based and requires no client download.
Users log on, specify airtime, then call a special number. The computer screen lists the phone numbers of guests or listeners calling in, and the host can put as many as six on the air at once by clicking a mouse.
Unlimited participants can listen in and can download a podcast version later.
Previous shows can be streamed, downloaded directly or subscribed to as podcasts via RSS through any podcatcher like Juice or iTunes.
Condé Nast Portfolio referred to BlogTalkRadio as a site that "has become the dominant player in the latest media trend, one that allows anyone with a Web connection to host a talk show on any topic at any time of day. It is the newest form of new media; the audio version of the internet blog."
