16 Years Ago, The Big Bang Theory Broke Its Biggest Sheldon Rule & Changed the Show Forever

As a long-time fan, I’ve always been fascinated by how The Big Bang Theory changed over its twelve seasons. Some of those shifts were clearly planned – like watching Howard mature from a bit of a ladies’ man into a loving husband and father, or seeing Penny really find her footing career-wise. But other changes felt more organic, like the writers were discovering the story as they went, trying to keep things fresh. That’s when they started bringing in new faces – characters like Stuart Bloom, played by Kevin Sussman, and Bernadette Rostenkowski, brought to life by Melissa Rauch – which really helped keep the show evolving.
