The Big Debate was hosted by Ed and Oucho every Wednesday in the early days of the CBBC Office generation of CBBC.

It was simply random things that were in the argument for instance - What's better? Hammers or Crisps. Upon this they would ask the veiwers to email in what is better and why. Some would be read out. The one with the most votes obviously won.

At some point a 'Randomiser' was used to select what the debate would be about.
