The once desktop-only Spreecast launched in 2011 as a forum for users to have public conversations with each other. Unlike video platforms like Skype, which let users chat privately, or    live streaming sites like uStream or stin.tv,     which let you watch live events, Spreecast is more like a 1960s party line updated for the     21st century. 
 How it works: Users set up a channel  pick a topic to discuss. ople can browse the list of channels  request to join in an interesting video     conversation. That request must be approved by the conversation’s host, or they can participate in the chatroom alongside the video. Spreecast can host up     to four simultaneous streams, so four people can appear on the feed at once. You don’t have to download a client or install any software; Spreecast is all     online. Or it has been, until now. 

o it’s for: News organizations like the ll Street urnal s Angeles es professional broadcasters like Scott are already using Spreecast to do one-hour shows or host journalist chats on current events. But anyone can use Spreecast, which is part of its appeal. Many of its regular users aren’t even registered, Spreecast CEO ff Fluhr says. Fluhr declined to disclose how many people have signed up, but said audience is growing a “significant number” of people are trying to access Spreecast on their smartphones. There are b conferencing services, private video platforms, streaming sites galore, but there are few sites that let you watch other conversations jump in, if you want. If you miss a chat, the site archives all conversations for future playback. “[ople] are having public forum conversations; it’s like the future of the watercooler,” says Fluhr, who also founded ticket-selling site StubHub. “You might gather around talk about a game that happened last night or a current event like the bombings in Boston or the new pope. That’s the kind of conversation you can find on Spreecast every day.” That democratization of current events is now going mobile. Spreecast’s mobile users will be able to watch chat along with broadcasts, a future version of the app will in a few months let viewers join in on camera.
