My name is Nathan and I have a YouTube channel, I wonder how do I get authorization to broadcast the Xbox at E3 2015 conference on my YouTube channel?
Try contacting Microsoft Support, maybe they can shed some light. If they don't know anything, maybe Xbox support?
For this, you will need to contact the PR office.
Here's their details:

Hope that helps!
