The villa-based reality dating show that began in the UK in 2005 is Love Island.
The original British series premiered on ITV in 2005 and was hosted by Patrick Kielty. It initially featured celebrities living together in a villa and competing in a dating environment. The modern version, which launched in 2015, uses members of the public and focuses on couples who must form relationships while facing new arrivals and public votes.
Love Island is sometimes confused with the similarly titled American series of the same name, but the British programme became the central international franchise. Its format has been adapted in countries including Australia, the United States, Germany and Spain. Contestants are commonly called Islanders, and coupling ceremonies determine which participants remain in the villa.
The show became particularly influential in British popular culture because viewers could vote on couples, eliminations and other outcomes. Its combination of romance, competition and serialized social drama helped make it one of the best-known modern reality formats.
