With Big Brother back on TV, time to look back on what was arguably the Reality fore-runner, Sylvania Waters, which was made by the BBC in Australia in 1992.
It sent the Donaher family in pop culture history, as this ABC News report illustrates.
Star Noeline Donaher even recorded a pop single to hit back at so much media intrusion into her life.
It was also a heavy inspiration for Kath & Kim.
Big Brother also followed 1998’s House from Hell, which began as a radio contest by Andrew Denton and Amanda Keller before being a 10 series.
