I think Big Brother UK has went in Chapters.
Big Brother 1 to 4 was the Expierment.
You know, when people just wanted to go in to see what it was like..But near the end of this chapter we started to get people going in for fame.
Big Brother 5 to 7 was the Entertaiment.
Probley the best Chapter, when people went in for fame but also the producers upped their game and gave us brilliant Tasks and Twists.
Big Brother 8 to 10
Jade Goody and Shilpa made BB suffer, The ratings died and this is the Chapter that each series the ratings started to fall more and more.
Possibly the Final Chapter 
My Quistion is about the Final Chapter,
BB8
3.9 Million Average
BB9
3.6 Million Average
BB10
2.5 Million Average
So out of them 3 which do you think has been the most Entertaining?
My Top 3 out of those are:
1) Big Brother 9
2) Big Brother 10
3) Big Brother 8
