When The Big Bang Theory hit screens in 2007, audiences were introduced to a world where comic books and theoretical physics collided in the best way possible. Over 12 seasons, the show, created by Chuck Lorre and Bill Prady, became a pop culture staple, proving that being a nerd was, in fact, pretty cool.
The show's success, which was largely due to smartly written quirky humor, also paved the way for an expanding universe of spin-offs. If you're looking to dive into all the series this franchise has to offer, here's a comprehensive guide to each show in the order they premiered and find out where to stream them all online.
The Big Bang Theory
The Big Bang Theory chronicles the lives of Leonard Hofstadter (Johnny Galecki) and Sheldon Cooper (Jim Parsons), two brilliant yet socially inept Caltech physicists who spend their free time geeking out over comic books with their equally awkward friends, aerospace engineer Howard Wolowitz (Simon Helberg), and shy an astrophysicist Rajesh Koothrappali (Kunal Nayyar). Everything changes when Penny (Kaley Cuoco), a confident and street-smart aspiring actress, moves in next door.
Young Sheldon
In 2014, fans curious about Sheldon's early years were treated to Young Sheldon, a heartfelt prequel series exploring his childhood in East Texas. Iain Armitage took on the role of a young Sheldon Cooper as he struggles to fit in with his peers. The show also focused on Sheldon's mother, Mary Cooper (Zoe Perry), his father, George Cooper Sr. (Lance Barber), his feisty Meemaw Connie Tucker (Annie Potts), and his siblings, Missy Cooper (Raegan Revord) and Georgie Cooper (Montana Jordan).
Georgie & Mandy's First Marriage
Expanding the Big Bang Theory universe further, Georgie & Mandy's First Marriage shifts the spotlight to Georgie Cooper (Montana Jordan) and Mandy McAllister (Emily Osment). First introduced in Young Sheldon, Georgie and Mandy's relationship progressed when an unexpected pregnancy brought them closer together. Like the title suggests, the couple eventually married, which set the stage for a successful first season. The show has since been renewed for a second outing.
Untitled Spin-off (In Development)
A new Big Bang Theory spin-off is currently in development, helmed once again by Chuck Lorre. While details remain under wraps, early reports suggest the show will shift focus to supporting characters from the original series, such as comic book store owner Stuart Bloom (Kevin Sussman), his nerdy and sharp-witted girlfriend Denise (Lauren Lapkus), and geologist Bert Kibbler (Brian Posehn). It is unclear whether main cast members from the flagship show will appear in the spin-off.
