Young Sheldon is a single-camera comedy from The Big Bang Theory co-creator and executive producer Chuck Lorre and executive producer Steve Molaro, who will executive produce the show along with Jim Parsons and Todd Spiewak:

For 9-year-old Sheldon Cooper (Iain Armitage), it isn't easy growing up in East Texas. Being a once-in-a-generation mind capable of advanced mathematics and science isn't always helpful in a land where church and football are king. And while the vulnerable, gifted and somewhat naïve Sheldon deals with the world, his very normal family must find a way to deal with him. The Big Bang Theory's multiple Emmy Award winner Jim Parsons narrates as Adult Sheldon. This single-camera, half-hour comedy gives us the chance to meet Sheldon in childhood, as he embarks on his innocent, awkward and hopeful journey toward the man he will become.

YOUNG SHELDON stars Iain Armitage as Sheldon, Zoe Perry as Mary, Lance Barber as George Sr., Raegan Revord as Missy and Montana Jordan as Georgie Jr. The Big Bang Theory's multiple Emmy Award winner Jim Parsons narrates the comedy as Adult Sheldon.

And in a final piece of good news for The Big Bang Theory fans, CBS chief executive Les Moonves said today at the Upfront that he hoped the show's recent two season renewal would not be its last. Moonves mentioned Everybody Loves Raymond as an example of a hit show which could have stayed on the air longer than it did.
