Baker has questioned the claim that his show, 'The Treehouse', would be cut down to save BBC money, when the corporation spends so much on TV adverts for their Radio 1 DJs.
The radio and TV veteran already has some famous friends in his corner. Stephen Fry called the BBC "dickwits" for their decision. Ross Noble called on the broadcaster to celebrate its talents.
Rob Brydon joked that he was glad Baker was going, as he "had it up to here with his wit, warmth and originality".
Digital Spy today launches a petition to try and save Baker's regular radio show. Baker himself is being 'inducted' into the radio Academy Hall of Fame next week.
It is our strong belief that such a talented and cherished show should be celebrated, not axed.
"We don't want to leave. We've been told to leave by people we don't know," Baker said at the end of today's final show. "People who don't listen to the show... and certainly don't listen to you."
Only 16 months ago Baker announced that he had been given the all-clear, after receiving treatment for throat cancer.
"It is an enormously absurd way to earn a living, and you can never lose sight of that," Baker said of his job in radio at the time.
If you would like to join the campaign to ask the BBC to continue Baker's show, please sign our petition below. We will be passing the petition to the BBC.
Additionally, here are some ways to contact BBC London if you'd like your opinion to be heard.
