BlogTalkRadio is a web-based platform that allows callers to host a live call-in Internet broadcast using a computer and a phone. BlogTalkRadio is entirely web-based and requires no client download.

Howard Kurtz, in his Media Notes column in The Washington Post wrote about BlogTalkRadio that "The process is nearly idiot-proof. The host logs on to a Web page with a password, types in when he wants the show to air, and then -- using a garden-variety phone -- calls 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. Listeners can download a podcast version later."

The service allows up to five callers at a time, although unlimited participants can listen in.

Shows stream directly from the host page during live broadcasts and are archived as podcasts. Previous shows can be streamed, downloaded directly or subscribed to as podcasts via RSS through any podcatcher like Juice or iTunes.
