Beck said:

Since launching GlennBeck.com over 12 years ago, we have tried to stay ahead of the curve by offering Insiders some of the most innovative, entertaining, and accessible features online. Insider Extreme will revolutionize the medium and give people a never-before-seen exclusive peek into my world. Scary, I know.

And speaking about the bonus fourth hour, Burguiere said:

Both Pat and I have spent over a decade working with Glenn and cataloging embarrassing stories about him. Now we finally have a place to tell them.
