A 19-year-old franchise from CBS is officially taking over HBO Max, with new data revealing just how popular its spinoff still is. CBS is home to a number of multi-series franchises spanning an array of genres, all of which have proven popular over the years. This includes numerous procedural series, such as the NCIS shows, alongside more high-octane thrillers, like FBI and CIA's shared universe. Dramas like Fire Country and Sheriff Country also count as core franchises, alongside the mystery comedy-drama Elsbeth. But The Big Bang Theory is one of the most prominent of CBS' ongoing franchises, having been part of the network's ecosystem since the original series premiered in 2007. While The Big Bang Theory aired a whopping 12 seasons overall, its spinoffs have kept it alive well past the original's ending. This includes the now-finished Young Sheldon, a show about Sheldon's life during his public school years before he got accepted into Caltech. But, since then, two more spinoffs have been released, one of which is now a massive hit on HBO Max ahead of its return to CBS. The Big Bang Theory Is Officially HBO Max's Biggest Hit The Big Bang Theory spinoff Georgie & Mandy's First Marriage is officially a major hit on HBO Max. A sequel to Young Sheldon, the sitcom follows Sheldon's older brother, Georgie, and his wife, Mandy McAllister, navigating married life, raising a child, and the 11-year age gap between the pair. According to data from September 12, 2026, Georgie & Mandy's First Marriage is a major success on HBO Max, becoming the Number 3 TV show on the platform in the United States. Its success reflects the continued success of The Big Bang Theory long after it ended. The sitcom's boost in popularity on the platform comes as the franchise sees multifaceted success on the platform. Another spinoff, the sci-fi comedy Stuart Fails to Save the Universe, has been airing weekly on the platform, with new episodes premiering every Thursday. It was renewed for season 2 halfway through its debut season, a strong sign for the franchise's continued success. As for Georgie & Mandy's First Marriage, the show's success emphasizes how big an audience it's garnered even outside the bounds of CBS. Georgie & Mandy Are About To Return CBS The sitcom's streaming success is coming at just the right time, too. Georgie & Mandy's First Marriage season 3 begins Thursday, October 8, 2026, on CBS. The episode count has yet to be announced, but if it mirrors previous seasons, then it will likely be 22 episodes in length. Its success on HBO Max means plenty of people are catching up on the series before its return, watching what Georgie and Mandy get up to after the end of Young Sheldon. With The Big Bang Theory spinoff doing so well on streaming, it seems like the franchise as a whole has plenty of life left in it. Georgie & Mandy's First Marriage, coupled with Stuart Fails to Save the Universe, delivers an experience on streaming that's clearly managed to captivate a wide audience. Because of how well the CBS sitcom has performed, it appears the franchise's strong performance will remain multifaceted into the foreseeable future.
