The reason that The Miz was selected as the host of this year's SummerSlam PPV is that he is looked at as the top social media representative for the company. The company wants to make a big social media push for the event, and Miz is a big part of that. The Miz will be using Google Glass during the PPV, which will allow him to send photos and videos to various social media platforms.
"We can use social media as the glue that connects all of these things for our fans who can't be in Los Angeles as well as the fans who are there. It creates a unified experience we weren't able to have before."
