Taskmaster is a British comedy panel game show created by comedian and musician Alex Horne and presented by both Horne and Greg Davies. In the programme, a group of five celebrities – mainly comedians – attempt to complete a series of challenges, with Horne acting as umpire in each challenge and Davies, the titular "Taskmaster", judging the work and awarding points based on contestants' performances. The concept for the programme was first created by Horne for the Edinburgh Festival Fringe in 2010; he later secured a deal with Dave to adapt it for television with the first episode premiering in 2015. After the ninth series in 2019, the programme was acquired by Channel 4. The programme has completed sixteen series as well as three Champion of Champions specials and four New Year's Treat one-offs by January 2024, and is set to continue for at least five more series until 2026.
