CBS’s beloved sitcom The Big Bang Theory aired its finale in 2019 after 12 seasons and 279 episodes. The series followed the awkward evolution of the friendships between physicist flatmates Leonard and Sheldon, their geeky mates, aerospace engineer Howard and astrophysicist Raj, and their waitress/neighbour Penny. The series quickly became a pop culture phenomenon, captivating audiences with its clever humour, incorporation of real scientific knowledge, and its ability to make complex topics fun and relatable. 

Since the series’ end, CBS has produced a backstage retrospective, two prequel series, and has one more spinoff in the works. With so much new Big Bang content circulating the cosmos, be sure to check out the guide below to find out how to watch every Big Bang Theory TV show and spinoff in order, and see all the streaming options in the United Kingdom.

How To Watch 'The Big Bang Theory' In Chronological Order

Watching The Big Bang Theory franchise in chronological order means starting with the prequels and finishing either with the backstage retrospective or with Stuart Bloom’s still unreleased solo series.  

  • Young Sheldon

  • Georgie & Mandy’s First Marriage

  • The Big Bang Theory

  • Unraveling the Mystery: A Big Bang Farewell

  • Stuart Fails to Save the Universe

However, if you prefer to watch all of The Big Bang Theory shows and spin-offs in release order, check out the list below.

The Big Bang Theory is where it all began for CBS. After 12 seasons on the network, the cast of lovably awkward nerds captured hearts and minds around the world while exploring themes of friendship, scientific research, relationships, and everyday struggles while consistently bringing the laughs.

The sitcom follows the daily lives of Caltech physicist Sheldon Cooper (Jim Parsons) and his motley crew of friends. Even before the sitcom ended in 2019, it was clear that neither CBS nor the fans were ready to say goodbye to the Big Bang universe anytime soon, so the network went on to create several spinoffs.

If you’re looking to start your journey into the world after The Big Bang Theory, we recommend closing out that chapter with the 2019 TV special Unraveling the Mystery: A Big Bang Farewell. The heartfelt behind-the-scenes retrospective features lead actors Johnny Galecki and Kaley Cuoco and gives the series a proper sendoff.
Unraveling the Mystery: A Big Bang Farewell is not available for streaming.

Young Sheldon
Young Sheldon first started airing on CBS while The Big Bang Theory was in its 11th season and lasted for a total of seven seasons. The prequel series delves into the early life of Sheldon Cooper, one of the franchise’s most beloved characters, and explores his childhood and family life in East Texas. Sheldon’s brilliant mind and quirky personality often set him apart from his peers, and the series balances heartfelt family moments with humour, capturing the challenges and joys that shaped him into the character we see on The Big Bang Theory.
Georgie & Mandy’s First Marriage picks up the story where Young Sheldon left off, focusing on Sheldon’s brother Georgie and his now wife, Mandy. While the two got off to a rocky start with Georgie lying about being 17 in order to have a chance with the 29-year-old Mandy—not to mention her subsequent pregnancy—they finally worked out their issues, got married, and had their baby. This spinoff series focuses on the couple and their new life together with their daughter CeeCee while still living with Mandy’s parents.

The latest Big Bang spinoff, Stuart Fails to Save the Universe, takes audiences back to the present day and focuses on the awkward comic book shop owner Stuart Bloom. Although plot details are still scant, we know that Lauren Lapkus (Denise), Brian Posehn (Bert Kibbler), and John Ross Bowie (Barry Kripke) will all reprise their Big Bang Theory roles on this new series.

Here's the synopsis: Comic book store owner Stuart Bloom is tasked with restoring reality after he breaks a device built by Sheldon and Leonard, accidentally bringing about a multiverse Armageddon. Stuart is aided in this quest by his girlfriend Denise, geologist friend Bert, and quantum physicist/all-around pain in the ass Barry Kripke. Along the way, they meet alternate-universe versions of characters we’ve come to know and love from The Big Bang Theory. As the title implies, things don't go well.
