British reality show Big Brother will be going off air after 18 years. The latest season will be the last, the makers announced today on Twitter.

The nineteenth season went on air today. Spin-off show Celebrity Big Brother will also be drawing to an end, host broadcaster Channel 5 said, according to a BBC report.

The show was first aired in the Netherlands in 2000 and syndicated to several countries around the world the same year. The format remains broadly the same with local variations: a group of contestants is confined to a house for a limited duration of time. Their behaviour and social interactions are monitored throughout the day through surveillance cameras. The contestants nominate their housemates for eviction, which is then put to an audience vote.

In India, Big Brother is known as Bigg Boss. The eleventh season is being aired on the Colors television channel.

Indian actress Shilpa Shetty won the Celebrity Big Brother edition in 2007 after enduring a racist rant from her house-mates.

Endemol Shine, the producer of the reality show, said it was “disappointed not to reach an agreement with Channel 5”, but added that “the decision opens up a new chapter and we are excited about future possibilities for Big Brother in the UK”.
