"The powers behind Big Brother decided to run a third series, after the first and second series were a huge success. This year went ok, but many people preferred the original format. Big Brother changed the way the show worked for the third series by adding a house divide and splitting the group up. The final night was a big hit, with Kate just beating Jonny in a close vote."
