Big Brother — which attracted its biggest viewership in seven years this summer — will be back for a 14th season, CBS announced Wednesday.

The show, hosted by Julie Chen, puts a group of people in a camera-rigged house where they are taped 24 hours a day as they compete for the $500,000 grand prize.
