Fans of the hugely popular sitcom have said their final farewell to the show after it aired in the US.
Since first hitting screens in 2007, The Big Bang Theory has become one of the most successful comedies in TV history – winning seven Emmy Awards.
It initially centred around a group of awkward male scientists and their interactions with their new female neighbour.

Kaley Cuoco, who played neighbour Penny, who lives opposite Leonard and Sheldon (Jim Parsons) posted a video of the cast hugging, while fellow cast member Melissa Rauch said being in the show was “one of the greatest experiences of my life”.
One time child actress Mayim Bialik, who plays neuroscientist Amy Farrah Fowler added her voice, along with Jim Parsons, who posted a photo of the cast. Parsons has earned four Emmy wins and a Golden Globe for his portrayal of Sheldon Cooper, a theoretical physicist.

In 2017, the primary cast took pay cuts in order to boost the wages of Rauch and Bialik, who were earning a fifth of their salary.
Simon Helberg also posted an image of the cast hugging, while Kunal Nayyar’s post on Instagram simply showed empty rows of audience seats.
