Big Brother (US)

"Big Brother" is a long-running reality show on CBS where a group of contestants known as houseguests enter a house in Los Angeles, without being able to leave, or have contact with the outside world, and be monitored by cameras 24/7 while they compete in challenges, form alliances, and vote each other out of the house in the hopes of winning the $500,000 grand prize. They are not allowed to leave the house or its' backyard for any reason, they cannot see or read magazines or newspapers, no radios, no computers, no phones, no I pods or MP3 players and only the HOH is given a small portable CD player to listen to CD's left in the HOH room for them.
