Reality TV and controversial, OMG moments go hand in hand. They're the primary reason you watch The Real Housewives of Atlanta online (for example).
In the early days, though, such moments weren't nearly as common or explosive. The Real World has nothing on some of the scandals of modern times.
Lately, it seems like we're dealt one jaw-dropping reveal, moment or conflict after another. So many it's almost become a struggle to keep up with them all.
That said, here are 19 of the biggest reality TV scandals of all time:
Not all shockers take place with the cameras rolling, of course.
Jon and Kate Gosselin imploded off camera, while TLC just canceled Here Comes Honey Boo Boo because of June Shannon dating a child molester.
That never made it to air ... and the show likely never would have if producers had known the tawdry extent of the Georgia matriarch's past relationships.
Bottom line? Don't expect an end to the madness anytime soon.
