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.
Record and re-share. Once you’re off the air, we’ll upload a public recording to your YouTube channel, and to your original Google+ post. This way it’s easy to share and discuss your broadcast after it’s over.

The feature will be gradually rolling out to users worldwide over the next few weeks, and Google suggests some public hangouts that you can tune in to while you’re waiting to gain access yourself.

These include shows with Conan O’Brien, Jamie Oliver, and a special event on May 10 for the Global Poverty Project.

The possibilities of Hangouts on Air are near limitless – whether you want to hold a presentation, a virtual conference, panel or roundtable discussion, or even want to hold an online concert. Video bloggers and podcasters also have a new tool at their disposal for live blogging, interviews and more.
