On youtube I saw a clip of when Dani & Amber went on a game show on BBUS8. Then I decided to watch BB8 which was easily accessible on youtube at the time + other seasons. This was during the summer of BBUS12.
Aside from binge watching a few seasons that summer (and more over time), I was a very, very casual fan for a while (I got a few friends into it for like 2-3 seasons each but they all only liked BB12 and gave up on the show lol). But I slowly got even more into it and prob became sort of a "superfan" around BBUS16 before joining this site and starting to watch live feeds for BB17.
Raph being a member here and getting on to BBUK is what got me into the UK version which is a good show as well.
