We all know that the three things that 'killed' C4 BB were the combination of Nikki being able to return and be eligible to win, the CBB5 racism row and then the BB8 all female launch which was mostly filled with 'fame hungry wannabees.' This resulted in the ratings decline over the last 3 years on C4 BB and resulted in C4 axing it.

After that, you could argue that BB had already been 'killed' - but for arguments sake BB14, CBB14, CBB15 did really well in the ratings after a worrying few years and then BB17 also improved in the ratings, providing evidence the show was building itself back up after Timebomb so C5 BB was doing 'okay' by it's low standards.

Then Bear comes along, behaves despicably, bullies majority of his fellow housemates and then wins the series. People decide to switch off. Intense rumours follow for an 'All Stars' series of CBB with big former names rumoured including Katie Price, Perez Hilton and Katie Hopkins (the trio were a fixture in C5's most popular series CBB15). The 'All Stars' line up for said CBB series instead includes names such as Jasmine Waltz and Coleen Nolan. People decide to switch off this series and not watch due to the disappointing line up. THEN the next civilian run of the show BB18 features a large number of 'civilians' who are actually not civilians. Many have featured on other television shows and have large social media followings and would be able to qualify for the celebrity version of the show. Many people decide to switch off - hence the low ratings.

SO IN SHORT - the 3 things that 'killed' C5 BB were Bear winning CBB18, CBB19 having a disappointing 'All Star' line up and then BB18 being filled with people who could have qualified for the celebrity show which already has 2 runs a year.
