The show Big Brother, which forces a group of people to live in a house together and vote off one of their housemates every week has led to a one marriage, several long term relationships, and countless long term friendships.
The Biggest Loser has led 2 sets of couples who met on the show to get married, while The Amazing Race has led to 10 marriages. Although, most of the couples knew each other going into the race.
The show Survivor, which features contestants being put into tribes on a deserted island as they fight for survival has led to more marriages and life long friendships that anyone can even keep track of. There have been at least 10 confirmed marriages.
It turns out that if you're looking to find love on a reality TV show, you'll find your soul mate as long as you compete on pretty much any other TV show than the one trying to set you up with your soul mate.
