[Underscore]

In full, mine was BB13! I was 11...

I remember watching snippets of C4 ones when I was very little. I can always remember watching the BB7 house (I was 5!!)

[Shaun]

BB3. Caught bits of BB2 but didn't watch it regularly.

[BBUK-Fan]

BB17 I watched fully on TV but went back and watched most of the others online

[y.winter]

BB11, and since then I'm still catching up old series. Not many left

[Littlegreen]

BB1

Sada's eviction was my first ever episode.

[Cal.]

It was always on in my house from BB1 but the first series I watched was BB7. I accidentally voted for BB6 though.

[hijaxers]

BB1 long time devotee

[Babayaro.]

I don't get how 6/7 year olds can be watching BB lmao, especially any of the Channel 4 series

Mines was BB12 when I was 13/14, but have watched nearly every series since.

[Lostie!]

BB7 after catching little bits and pieces of BB6. I vividly remember switching it on once just as Makosi was running up the stairs after Vanessa

[LukeB]

BB5

[EspeonBB]

I saw bits of BB6 but the first series I fully watched was BB7

[TeenAngel15]

BB4! I'd have only been 6 at the time - although I do remember watching the BB3 final as a young child, but not an avid viewer. Looking back can't believe I was so involved. I was a HUGE Nush fan back in the day, and vividly remember the disappointment of Cameron beating Steph in the final.
