Rejoice, Young Sheldon fans. The show is officially getting more episodes in the 2018-2019 season. Some Big Bang Theory fans were worried that CBS couldn't pull off a sitcom about Dr. Sheldon Cooper's early years. But the plan paid off. And Young Sheldon has proven to be one of the biggest new shows in years.

CBS announced that the sitcom will return for a second season just this morning. Young Sheldon Season 2 is set for the upcoming fall slate, news that was released at the winter TCAs. CBS President of Kelly Kahl had this to say in a press release from CBS.

'Young Sheldon has made a huge impact on our schedule in the short time it's been on the air.While the show's DNA is clearly rooted in The Big Bang Theory, Young Sheldon has staked out its own place in the TV universe with a unique creative tone, brilliant writing and a gifted multi-generational cast. We can't wait to see Chuck, Steve, Jim and Todd's vision for how the Cooper family deals with Sheldon growing a year older... and smarter."

Young Sheldon isn't just a minor hit for the network. It is the most-watched new comedy on any network in 18 years. CBS decided to make the sitcom first renewal for the 2018-2019 season.

Young Sheldon is the #1 new comedy in viewers (16.17m), adults 18-49 (3.3) and adults 25-54 (4.9), and is the #2 comedy in all of television (behind only The Big Bang Theory). It has the best retention for any show ever out of The Big Bang Theory and has the best delivery of any new comedy on any network since the 1999-2000 television season. The show is a half-hour, single-camera comedy series. The cast includes Iain Armitage, Zoe Perry, Lance Barber, Annie Potts, Raegan Revord, Montana Jordan and the voice of Jim Parsons. The storyline shows The Big Bang Theory's Sheldon Cooper (Armitage) at the age of 9, living with his family in east Texas and going to high school.
