Just say this..
'BB20' 'Big Brother 20' or -
Big Brother 2021'.
I mean it sounds really really far away but if you think about it, only 5 more normal series
(and 11, yes eleven - m0re celebrityy series x 
)
to go until Big Brother UK turns 20.
But will it last that long?
Yes the show hasn't been doing too well - but it's still one of Channel 5's biggest shows, and for alot of people is the only time they even bother with Channel 5 - so in terms of advertising and total income, it's worth their while completely.
What we do know - is that Channel 5 have stated that the 'Civilian series isn't going anywhere' although we shouldn't take that as gospel, until next year when the contract is examined again after BB15, and we also know the head of Endemol recently stated that he wants Big Brother to continue for another 50 Years.. but he might not of necessarily meant BBUK.
Opinions?
