Check out this article from USA Today:
After initially offering the service to a limited number of users, Google is finally rolling out its Hangouts on Air feature to Google+ users around the world.
We've seen some great uses of people being able to publicly broadcast their hangouts, from celebrity interviews to showcasing non-profit initiatives.
Curious about what the new feature holds? Google explains:
"Broadcast publicly. By checking 'Enable Hangouts On Air,' you can broadcast your live hangout —from the Google+ stream, your YouTube channel or your website — to the entire world.
See how many viewers you've got. During your broadcast, you can look inside the hangout to see how many people are watching live.
It would be a bit of a juggling act amidst your showprep and the actual execution of your show, but I could see doing this before, during or after your airshift. It would also work nicely as a chatroom for people listening to pre-recorded programs. I've often wondered how I could create a real time experience for broadcasts of my Secret History of Rock show across the country.
Imagine the kind of community you could build! Think about it and if you have any ideas to share, please do.
