Channel 5's Director of TV Ben Frow says he wants to make sure the series remains as the Number 1 reality show.
"I do think Love Island gave us a little bit of a jolt this year," he admitted. "It's no big thing, they got a two week head start which made me f**king angry, frankly."
Speaking at the Edinburgh International Television Festival, Frow went on: "Big Brother is 17 years old, it'll be 18 years old next year, it's still going. I don't want to be the person who kills Big Brother...
"It's all good so far but we owe it to the viewers to ask 'How can we reposition this for the future? How can we keep surprising the viewer? How can we take something that is a great premise, filming people 24 hours a day, what can we do with it going forward?'
"I'd like to have that brave, big, bold, blue sky discussion with the makers of Big Brother.
"After this series is finished, we'll go 'In January it starts again, what could we do that'll make us leaders?'"
He declared: "Big Brother has been the number 1 reality show for 17 years, I do not want to be second, I want to keep being a leader in terms of reality."
Big Brother and Celebrity Big Brother will both return to Channel 5 next year.
