Google launced "YouTube Live" today, which will integrate live streaming capabilities and discovery tools directly into the YouTube platform. This begins with a new YouTube Live browse page, where you can always find the most compelling live events happening on YouTube and add events to your calendar. Subscribe to your favorite YouTube live-streaming partners to be notified of upcoming live streams on your customized homepage.
Also, Google started gradually rolling out "live streaming" beta platform, which'll allow certain YouTube partners with accounts in good standing to stream live content on YouTube. The goal is to provide thousands of partners with the capability to live stream from their channels in the months ahead. Partners interested in learning more about the livestream experience can check out post on the Partner Communications Hub.
