Talking with Jessica, I realized how easy it had been for me to kind of put all 12 years of my time on Big Bang Theory under one general umbrella, as it were. The questions she asked and the information she'd reveal to me from someone else she'd interviewed forced me into a frame of mind where each season - and sometimes each episode - became it's own, separate entity again. Frankly, it turned into a version of therapy I hadn't realized I'd needed and couldn't have known how much I'd enjoy." -Jim Parson

The Big Bang Theory is a television phenomenon. To the casual viewer, it's a seemingly effortless comedy, with relatable characters tackling real-life issues, offering a kind of visual comfort food to its millions of dedicated fans.

But the behind-the-scenes journey of the show from a failed pilot to a global sensation is a fascinating story that even the most die-hard fans don't know in its entirety. THE BIG BANG THEORY: THE DEFINITIVE, INSIDE STORY OF THE EPIC HIT SERIES is a riveting, entertaining look at the sitcom sensation, with the blessing and participation of co-creators Chuck Lorre and Bill Prady, executive producers Steve Molaro and Steve Holland, as well as Johnny Galecki, Jim Parsons, Kaley Cuoco, Simon Helberg, Kunal Nayyar, Melissa Rauch, Mayim Bialik, and more. Glamour senior editor Jessica Radloff, who has written over 150 articles on the series (and even had a cameo in the finale!), gives readers an all-access pass to its intrepid producing and writing team and beloved cast.
