Britain's Got Talent is a British talent reality television series that first aired in 2007. As of 2 June 2019, there have been thirteen completed series. The show has been spun off around the world under the Got Talent franchise. The competition is open to people of all ages who possess a talent. After the initial rounds of auditions, successful contestants are narrowed down by the judges.

In the first series, 24 contestants made it into the three semi-finals, and in subsequent series this has been increased to 40 (45 in series 6–10) contestants across five live shows. The act which receives the most public votes in each semi-final goes through to the final, with the second finalist being decided by the judges from the second and third most popular contestants. In series 6, a "wildcard" element was introduced. This is where judges pick an eliminated act from the semi-finals, and that act is sent through to the final. In series 6, the wildcard act selected was The Mend. In series 7, the wildcard was Steve Hewlett and in series 8,al Jon Clegg. Series 9 featured a second wildcard, voted for by the public from the five acts who lost the judges' vote in the semi-finals.{{Cite web|url=http://www.itv.com/britainsgottalent/insider/round-up-theres-plenty-of-drama-on-fridays-show|title=Round-up!
