"Nasty" Nick Bateman was the subject of headlines in tabloids and broadsheets alike in 2000 when he was kicked off the first series of Big Brother for trying to influence the housemates' nominations.
That series was won by carpenter Craig Phillips, who donated his £70,000 prize to a friend to help her pay for a heart and lung transplant.
Former nun Anna Nolan, runner-up in series one, went on to present a number of TV shows including Anna in Wonderland on BBC Three.
Such was the show's popularity that former contestants from the first few series regularly appeared on other TV shows.
Helen Adams - who coined such phrases as "I love blinking, I do" - and designer Paul Clarke became the show's first on-screen couple in series two in 2001.
In 2002, the UK was introduced to dental nurse Jade Goody who went on to become Big Brother's most famous former housemate.
In the same year, Scotsman Sandy Cummings was the first contestant to escape from the Big Brother house, scaling a garden wall to make his exit from the show.
In 2004's Big Brother Five, student Stuart Wilson and former glamour model Michelle Bass - seen here promoting Children in Need - provided the love interest.
Portuguese contestant Nadia Almada won that series to become the show's first and only transexual winner.
Put in the Celebrity Big Brother house as a token non-celebrity in 2006, Chantelle Houghton won the series and went on to marry fellow housemate and pop star Preston.
