The iconic show put a range of contestants into a house, shut off from contact with the outside world. The group of between 12 and 16 houseguests would then gradually be evicted according to a public vote.
“The social-experiment show was a huge success as a result of its 24-hour live video feeds and relatable TV content,” said Nick Baker, broadband expert at Uswitch.com.
“It’s fascinating to see just how significant the show has been for a number of contestants.
“For example, legendary contestants such as Alison Hammond found tremendous fame, gaining 1.1 million Instagram followers. Alison went on to host This Morning and Loose Women, while also making appearances on Strictly Come Dancing and I’m a Celebrity...Get Me Out of Here!”
Who are the most popular Big Brother UK contestants of all time?
The research analysed the Instagram followings, IMDb credits, and the number of days spent in the house of each previous Big Brother contestant, starting at the beginning with series one all the way through to season 19.
These factors were used to determine a score out of 10 for each contestant and inform the rankings of the most popular Big Brother contestants of all time.
Taking those three factors into account, the most popular Big Brother contestant of all time is Aisleyne Horgan-Wallace of season seven, with a contestant score of 8.8 out of 10.
Aisleyne placed third in her series of Big Brother, back in 2006, yet she still remains in the spotlight with an Instagram following of 593,000 and an online career on TV, with a total of 61 IMDb credits.
Second place is shared jointly between Deana Uppal and Kate Lawler.
