Long before its Channel 5 stint, Craig became the first person to win the show when it aired on Channel 4 in 2000, which was hosted by Davina McCall.
The nation was griped over his fallout with Nasty Nick, who was dubbed the ultimate villain at the time, and while revealing that the pair are now "great friends", Craig said the criteria for casting housemates isn't the same.
Craig, who made a surprise return to the Big Brother house as part of a task last week, told The Sun: "I still watch Big brother sometimes but it's lost its edge. They've bought in weirder and wackier people desperate for fame, which is an insult to the public."
Before entering the famous Elstreee compound, Craig was working as a building company boss. He went into the house to win the prize fund for his friend Joanne Harris, who had Down's Syndrome.
Craig said winning the show was "terrifying", and after spending 97 days away from home on a personal tour, "I'd never been so lonely in my life".
With newfound fame, Craig launched a career as a DIY expert, and also hosted 60 Second Makeover. Now, he runs his own production company and is an ambassador for a tradesman website.
