Google continues to remove characteristics of Google Plus. This time, the company is shutting down Hangouts On Air and replacing it with YouTube Live.
So from September 12, those who want to start live broadcasts should use YouTube Live.
Google says:
“Live events cannot be scheduled on Google+ after September 12, and you will need to move your existing events after September 12 to YouTube Live.
Hangouts On Air features Q&A, Showcase and Applause. which will not be transferred to YouTube. So Google encourages broadcasters to use Google Slides for Q&A, and social media to collect questions before the event.
