Career: Carr began performing on the stand-up circuit, doing up to 300 shows a year for three years, before taking his act to the Edinburgh festival in 2002. This brought him to the attention of TV bosses, and before long he was presenting series such as Your Face or Mine and Distraction. Since then, he's rarely been off TVscreens, hosting the first run of the Friday Night Project, 8 Out of 10 Cats and numerous Channel 4 list shows. He's also made a move into acting, appearing in Alien Autopsy, Confetti, Stormbreaker and Telstar. He is one of Britain's busiest comics and his DVDs are big sellers.

Career: In 2003, Richardson won his heat of the BBC New Talent Comedy Search, and a year later did well in the Laughing Horse New Act of the Year competition and J20 Last Laugh Comedy Search. Encouraged by these successes and kind words from Jasper Carrott and Dave Spikey for a performance at the Criterion Theatre in London, his confidence grew. More stand-up followed, including appearances at the Edinburgh Fringe Festival. He went on to feature on numerous radio shows before moving into TV. Richardson appeared on Never Mind the Buzzcocks and Have I Got News For You before becoming a team captain on 8 Out of 10 Cats. He's since published his first book, It's Not Me, It's You! and taken part in various documentaries.

Career: Gilbert was nominated for the Perrier Newcomer award for his first solo show in 2005 at Edinburgh entitled 1984. He has since performed worldwide, and was the first Western comedian to appear in Taiwan. He has featured several times on shows such as Mock the Week, Have I Got News for You, 8 Out of 10 Cats and Never Mind the Buzzcocks. Other TV projects include Live at the Apollo, Ask Rhod Gilbert and Rhod Gilbert's Work Experience. He also presents a weekly show on BBC Radio Wales and became the presenter of Never Mind the Buzzcocks in September 2014.

Career: His success as a stand-up was crowned when he won an award at the Edinburgh Fringe Festival. He came to the attention of TV bosses after a stint on the radio. Lee was cast in The Sketch show alongside long-term collaborator Tim Vine. After a short-lived stint presenting They Think It's All Over, Mack and Vine began work on Not Going Out. The series revolves around two friends with opposite backgrounds and personalities, much like the two comics themselves. Mack has recently become a regular on comedy panel shows such as Would I Lie to You? and Have I Got News for You. He also has sell-out tours and best-selling DVDs to his name.

Career: Riley's big break came in 2008 when she was chosen from more than 1,000 applicants to replace Carol Vorderman on Countdown. She presented her first show alongside Jeff Stelling in January 2009, and reached her 1,000th episode in June 2013. Away from the numbers and letters on Countdown, she began co-hosting The Gadget Show alongside Jason Bradbury in June 2013. She was a contestant on Strictly Come Dancing in 2013 and was the fifth celebrity to be eliminated.

Career: Osman has worked behind the scenes as an executive producer on a number of TV programmes, including Deal or No Deal, 8 Out of 10 Cats, and 10 O'Clock Live. As the UK creative director of TV production company Endemol, he pitched the quiz Pointless to the BBC. As a way of explaining the rules, he played the co-host during a run-through. He was asked to do the role for real when the show was commissioned. Pointless started on BBC Two in 2009 and was an immediate hit. It quickly made the switch to BBC One. Since being in the spotlight on Pointless, he has made guest appearances on QI, Have I Got News for You and Would I Lie to You? He also guest presented an episode of The One Show alongside Alex Jones.
