This spring, The Big Bang Theory will finally say goodbye after 12 long seasons. But CBS is staying in the Sheldon business. Though Jim Parsons' version of the character is getting ready for the dustbin of sitcom history, the hyper-intelligent being will be sticking around for a little longer. CBS has officially renewed Young Sheldon for Season 3 and Season 4. Said Kelly Kahl, CBS Entertainment.

"Thanks to Chuck Lorre's and Steve Molaro's outstanding creative leadership, Young Sheldon has been a powerful performer for the Network with an audience that towers over most of the television landscape."

CBS decided to double down on their hit comedy, not just renewing for the next season, but all the way through Season 4. The hit spinoff is currently in its sophomore season. Season 3 will beginning with the 2019-2020 broadcast season. Added Thom Sherman, Senior Executive Vice President of Programming.

"The Coopers are portrayed by an amazing cast, and we are looking forward to having the gifted writing staff mine even more of Sheldon's hilarious backstory and the warm family dynamic that has made this comedy a favorite with audiences for the past two seasons."

Young Sheldon is television's #2 most-watched comedy, behind only its lead-in and precursor, The Big Bang Theory. The series averages over 14.5 million viewers each week. It stars Iain Armitage, Zoe Perry, Lance Barber, Montana Jordan, Raegan Revord and Annie Potts. Chuck Lorre, Steven Molaro, Jim Parsons and Todd Spiewak are the executive producers for Chuck Lorre Productions, Inc. in association with Warner Bros. Television.

It's 1989 and 9-year-old Sheldon Cooper has skipped four grades to start high school along with his less-intellectual older brother. As he struggles to be understood by his family, classmates and neighbours, his mother arms him with the best tool she can come up with: reminding bullies his dad is the football coach and his brother is on the team. His twin sister doesn't share his exceptional mind, but she has a much clearer vision of what life has in store for the young genius. Jim Parsons, who plays the adult version of Sheldon on The Big Bang Theory narrates.

This spring, CBS will air the final episodes of long running hit The Big Bang Theory, closing out everything with Season 9. With Young Sheldon kicking off in the late 80s, new episodes will presumably flow into the 90s for a good torch of nostalgia as Sheldon continues to grow his brain and nerd out over some of the more significant pop touchstones of the era.
