Apparently... The iconic reality TV programme will be back for what could be their last series later this year, and they are making sure they go out with a bang. Channel 5's contract for the show comes to an end this year and, while talks are still ongoing with production company Endemol, they are yet to re-sign the programme. Sources tell Daily Star Online the civilian series of Big Brother 2018 has been confirmed to start either the last week of August, or the first week of September. This means a Friday launch night would take place on August 31 or Septemeber 7. "Big Brother bosses are open about the fact they don't want to take on Love Island in the ratings," a source explained. "They have revamped the casting team behind the scenes in a bid to shake things up in terms of casting new housemates. "The show won't start until the end of August at the very earliest." But that's not all. The controversy-loving show which once gave us stars like Jade Goody and Aisleyne Horgan-Wallace, is set to be the longest ever. Currently Big Brother 8 in 2007 was the longest lasting 94 days – just over thirteen weeks. "Everyone is being told to leave at least twelve weeks free," a second insider added. "They are saying it could be the longest ever and are making people aware a fourteen-week stretch in the house is highly possible." Daily Star Online first revealed in December how BB was facing axing its traditional June launch date. A source at the time said: "Last year was understandably disappointing in terms of ratings and they will want to avoid taking on Love Island." When contacted by Daily Star Online at the time, a rep for Channel 5 failed to deny both the schedule change and Love Island's influence simply saying: "We will confirm a launch date nearer to transmission."
