PowerPoint Live is now generally available — from microsoft.com by Derek Jo

Excerpt:

Earlier this year, we announced that Live Presentations was coming soon, and we are excited to share that it is now generally available on PowerPoint for the web.

When we first announced PowerPoint Live, we saw excitement from both enterprise and education customers around how this feature could be utilized during in-person events—conferences, lecture halls, corporate all hands, town halls, and more. Of course, the world has changed a lot since then. 

We know that as more physical events and meetings take place, PowerPoint Live will prove to be a very useful tool for connecting with your audience and communicating more effectively, which we are excited to show you. However, we also have tips below on how to use this capability now in remote work and learning scenarios.
