Journalist Grace Dent (her off The Guardian) takes a look at the impact of ten years of Big Brother, which started as a little-known show where ten housemates entered an environment of 24/7 filming. It then became a worldwide brand and the biggest reality show that has never been far from the headlines. Featuring interviews with Mark Frith, Paul Flynn, Carole Malone, Oona King, Peter Tatchell, Krishnan Guru-Murthy, Ian Hyland and a load of ex- BB housemates, Big Brother: A Decade in the Headlines examines how Big Brother has affected celebrity, diversity and television. Be warned; the new series of Big Brother starts on Thursday.
