Young Sheldon premiered on CBS in 2017 as a prequel to The Big Bang Theory, created by Chuck Lorre and Steven Molaro. Iain Armitage plays the nine-year-old Sheldon Cooper, with Zoe Perry, Lance Barber and Annie Potts in his Texas family. The series ran for seven seasons until 2024 and built a large second life on streaming and social media, where short clips are reposted as reaction material. Its mix of childhood, science and family comedy keeps lines and moments circulating long after broadcast.
