To mark the last ever episode of the hit series ‘The Big Bang Theory’, Channel 4’s in house creative agency, 4Creative, have devised an interactive test that will give the most loyal fans the chance to receive a one-of-a-kind diploma based on the show.

Adverts running across E4 social media accounts and channel continuity announcements will point viewers to the E4 YouTube page where our very own science professor, Magnus Frode, will take them through five questions to test their knowledge on the much-loved US comedy about a group of socially clueless scientists.

If a question is answered correctly then the player is directed to another video with the next question. But if they get the question wrong a video will appear showing the professor’s disappointment before they can try again. Once the player has answered all five questions correctly they are taken to a dedicated microsite where they can enter their name and download a personalised certificate which they can (smugly) share on their own social media channels.

The Big Bang Theory is E4’s most popular show, with series 12 currently averaging a massive 1.9 million viewers and an impressive 18.9% share of 16-34-year olds – the digital channel’s key demographic.

To ensure the series goes out with a big bang, two special programmes will also air on E4 as well as the finale on Thursday 23rd May. Hosted by Johnny Galecki and Kaley Cuoco, ‘Unravelling the mystery: A Big Bang Farewell’ at 7.30pm will give fans access to backstage secrets, followed by the hour-long series 12 finale and last ever episode of the hit comedy at 8pm. Viewers will then be treated to a celebration of everything ‘Big Bang’ related in ‘The Big Bang Theory of Everything’ from 9pm with celebrity fans sharing the love.

Christos Savvides, Executive Producer, Digital at 4Creative said: “The Big Bang Theory has been a huge hit for E4 and there’s a lot of excitement around the final episode. Our concept combines the science and nerdy-ness of the show, whilst building anticipation for the finale by driving engagement and rewarding fans with a memento for social kudos. BAZINGA!”

The final two episodes will be shown on E4 on Thursday 23 May at 8pm.
