The first series of Mock The Week made its debut on Sunday 5th June 2005. The format at that time was that Hugh Dennis and Frankie Boyle were team captains on the one side whilst Rory Bremner captained the other team. There were five episodes in this first series (it was due to be six however the last recording was cancelled due to a terrorist alert)
Following the success of the first series, the show returned six months later for a six-episode second series. The comedy was also boosted by a move into a prime-time slot on Friday night. The core panel remained un-changed with Hugh and Frankie on the one-side and Rory providing the impressions from the other side.
The Autumn series saw the show move into its now traditional Thursday night slot. There was another significant change too - over the summer Rory Bremner had decided to leave the show and so a new team captain was required. Regular guest Andy Parsons, who had already appeared in over half of the episodes up to this point, was the natural choice and so took to the centre chair on the right-hand side.
When, in January 2007, Mock The Week returned to BBC Two for a fourth series the producers decided to even things out so that both teams had two regulars and one guest each week. Russell Howard had made an instant impact in the previous series - to such an extent he had been booked for four out of the six episodes in series three. It was decided he would officially join Andy Parsons as a regular for this fourth series.
By the fifth series the show had really hit its stride; the regular five were working very well together, and ratings were continuing to rise. The BBC were so happy with the series and eager for it to continue that they commissioned an extended eleven episode series to fill BBC Two's schedules during the Summer and early Autumn.
With series five proving very popular with audiences, the BBC ordered another twelve episodes of Mock The Week to fill the Summer 2008 schedules. The regular team were all back, along with regular guests like David Mitchell, Michael McIntyre, Ed Byrne and Mark Watson. With another England manager to assess, a London Mayor to laugh at and an American Presidential election to decide there was plenty of material lined-up for them.
Mock The Week ran for 12 weeks in 2009. There may have been no Olympics in 2009, but the team were able to use the time to decide on their approach to Barack Obama as well as comment on the usual tabloid scare stories, reality TV controversies, the MP expenses scandal and the on-going 'credit crunch'.
Andy, Dara and Hugh returned for 6 episodes in June and July 2011. The show took a break over August to avoid the Edinburgh Festival and the news-free papers, before returning in September for another batch of episodes. For this second batch, Chris Addison was named as the official regular replacement for Russell Howard.
