CBS says it has renewed its U.S. reality TV competition series \"Big Brother\" for a 14th season. The show is to air next summer, the network said. Season 13 wrapped up Wednesday night with a 90-minute episode in which Rachel Reilly won the $500,000 grand prize. The series, which is presided over by Julie Chen, follows a group of people living together in a house outfitted with more than 52 cameras and 95 microphones recording their every move 24 hours a day. Each week, the house-guests vote someone out of the house.
