I have one television show I watch and I cant wait for it every week..  It is the CBS show survivor.  This is the reality show that has 16 people that get dropped off on an island.  Throughout the course of the series, the "castaways" participate in challanges for "rewards" or "immunity".  The participants are broken into 2 teams each with a unique name.  They battle the other team and eventually the 2 teams merge and all the remaining members compete against each other for a single, personal immunity rather then a team immunity.  

When they play for the reward challange, the reward is usually food, or an item that can help make their stay more comfortable (tarps, blankets, fishing gear, etc) 

When they compete for immunity, the losing team has to vote someone off the island.

When the teams get low on members, they merge into one team.  The last 8 people that get voted off become members of the "jury".  The jury gets to decide which one of the last 2 remaining members is most worthy of receiving the 1 million dollar prize.
