While CBS's Big Brother continues to pull in solid ratings in its 11th edition in the U.S., the show has slipped appreciably in the U.K., where it originated. The Channel 4 network, which carries it there announced today (Wednesday) that next year's season will be its last. The show debuted in 2000 and includes an interactive element that allows PC owners to view the goings-on in the "house" where the contestants are required to live for the season 24 hours a day.
