The Big Bang Theory spinoff, focusing on a young version of Jim Parsons' fan-favorite character, had the honor of being the first show to be picked up, with CBS ordering a full-season. And it's easy to see why: The premiere attracted 17.2 million viewers and a staggering 3.8 rating in the 18-49 demographic, making it the most-watched comedy premiere on any network since 2011. (The rating was also the highest for any new comedy since 2013. Bazinga!)
