It's 35 years since the first live fundraising event, on April 4, 1986.
The extravaganza had been founded the previous year by comedy scriptwriter Richard Curtis and comedian Sir Lenny Henry, in response to the famine in Ethiopia.
And in the three and half decades since, Comic Relief has raised more than £1.4 billion for good causes across the UK and Africa.
It's all about having fun and making the world a better place and, true to form, the event has always been well supported by kind-hearted people from across Colchester and Tendring.
We've dipped into our photo archive to pick out ten of our favourite pictures from the last decade.
