Big Brother is a hit reality television show in which a group of houseguests live under one roof in a custom-built house in Los Angeles, California with around-the-clock surveillance. It's really not a made-for-TV game show competition for the faint of heart, but the grand prize is $500,000, which gives houseguests a reason to isolate themselves from the outside world and deal with all the drama of their fellow housemates.
