Entertainment Weekly has voted "Survivor" as the best reality show ever! (6th Dec 2010)

Entertainment Weekly has voted

SURVIVOR (CBS, 2000-present)
By dropping 16 strangers on an island and letting them battle it out for a million dollars, Survivor changed the face of television for better or for worse more than any show this millennium. And the combination of exotic locales, backstabbing strategy, and hotties in bikinis has the series still going strong.
Best Season: 1, when the snake (Richard Hatch) devoured the rat (Kelly Wiglesworth).
