Big Brother is a television reality game show based on an originally Dutch TV series of the same name created by producer John de Mol in 1997. The show follows a group of House Guests living together 24 hours a day in the "Big Brother" house, isolated from the outside world but under constant surveillance with no privacy for three months. Since its US television debut in 2000, Big Brother has run continuously with at least one season of the show airing each year. It is currently the second longest running version in the world to have done so, after the Spanish version. On September 19, 2012, CBS announced that Big Brother was renewed for its 15th season in summer 2013. The 15th season will debut on June 26, 2013.
