Chuck Lorre and Bill Prady's nerd-centric sitcom amassed an astounding number of fans who helped it maintain its relevance, secure countless awards, and earn an enduring place in pop culture that few others share. In fact, to this day, the CBS hit is looked back on fondly as one of the 2010s defining television programs, and that assessment is well deserved in more ways than one.
