Big Brother 6, also known as Big Brother: Zero Privacy, was the sixth season of the Belgian version of Big Brother aired in the Flemish Region of Belgium on KanaalTwee. The show started on 7 March 2007 and finished on 4 June 2007 with a total duration of 92 days. The season started with duos. The concept of "Zero privacy" of last season was extended. A lie detector was installed and the lies of housemates were detected. The season was poorly received. Because of dropping ratings, the producers made changes. Halfway through the season, half of the housemates were evicted in a massive eviction and replaced with new housemates. The duo concept was abandoned after the massive eviction. Two actors were added as housemates to spice things up. The date of the live shows was reverted from Thursday
