The premiere of its 11th season, which aired right before Young Sheldon, averaged a 4.1 rating in its key demographic and 17.7 million viewers.
Jim Parsons, who famously portrays the adult Sheldon on Big Bang Theory, is an executive producer on Young Sheldon and narrates the show.
Young Sheldon, the prequel/spinoff of hit sitcom The Big Bang Theory, scores the biggest comedy premiere in four years, proving that the brand is still going strong, more than a decade later.
The Big Bang Theory did not start off with a big bang when it made its debut in 2007.
