I've watched them all except the 1st week of series 1, series 8 and the end of series 12.

All except 1st week of series 1
and only 1st week of BB9..then gave up on it as the Mario Lisa story was just silly

I've watched every series except Celebrity Hi-Jack.

I missed quite a few episodes of the series that just finished though as I just lost interest in it.

All of them

All of the regular series, minus BB12... because it was crap. Teen BB and Celeb Hi-Jack.

I've skipped quite a few of the celeb versions.

I've watched all of normal BB, not many of the celeb ones or spin offs.
I have watched with decreasing dedication since about BB8.

Dissapointing. Celeb hijack was fun.

All of them except teen big brother if that counts.

I've watched all the regular BB's and my favourite series ever was BB7.

All the celebrity BB's apart from the one with Jedward (I just couldn't)

Didn't see Teen BB or Celeb Hi-Jack.

i have watched since series 2 -- religiously watched since series 5.

All of them apart from Hijack. Still need to watch that in full. Only saw the launch,a few clips and the final

I started watching them all but stopped watching 13 and 15, I also didn't watch 2 weeks of 16 as I refuse to watch Helen woods.

The standard continues to decline both c5 and endemol are at fault. C5 for allowing endemol to give them a poor program and endemol for making such a poor show. It's time it was rested for a few years and brought back with a new production team.

All, apart from Teen BB.

I had my own one going on at home, which was stressful enough.

All except BB1.

All the proper ones. I'm an expert.

All of them.

All of the C4 series and just Secrets and Lies on C5

All of them up until the debacle that was the stinking Josie and JJ debacle.

I was a diehard fan but I was so repulsed at the winner and the manipulation that I stopped watching after that ..didn't watch BB11 &BB12.

Was very ill during BB13 so tuned in again, a way to break the monotony of my hospital stay.

This year has been risable...I still havent bothered to watch the final or BBOTS final either.

I actually think I'm done...

Celeb Hijack
Cant remember Teen BB at all so think I missed that

All the CBBs - though switched off the one with Mark Owen.

Normal BB - watched 1-7, dipped in and out of 8 and 9, not watched from 10 onwards

1, 2, 3, 4, 5, 6, 7, 8, 9, 11, 12, 14 complete
10 - gave up after the producers' desperate stunt to stir things up by putting Isaac in.
13 - gave up when Luke & Lauren were put up against each other after loads of cheating in the face to face noms.
15 - gave up when Danielle was evicted when Kimberly was in hospital and housemates were being evicted without public votes.
16 - gave up when the unnominated housemates were put up for the quadruple eviction

CBB 3, 4, 6, 7, 12, 13, 14, 15 - complete

CBB 1 & 2 - didn't watch as these were just charity events rather than proper BBs.
CBB5 - gave up when the Goodys entered, resumed watching after the Shilpa incident
CBB8 - never watched as there was no-one in it that appealed to me
CBB10 - switched off after a week as Jasmine Lennard was so foul. Did not resume watching after her exit.
CBB11 - switched off when it became the Speidi Show

Teen BB - complete
BB Panto - complete
Celebrity Hijack - complete
UBB - complete

forgot to add Ultimate BB

All of the non-celeb ones, and only a couple of the Celeb ones.......I have tried with the Celebs but unless I know them, I lose interest quickly........the best Celeb one for me was Julian Clary, ? Nolan, Julie Goodyear etc.

Never forget the sight of Julie eating a banana, held by a six pack adonis in tight gold shorts.......

3, 4, 5, 6, 7, 8, 9, 10, 11, UBB.

Saw a few episodes on C5 and knew it wasn't for me anymore.
