Well, I've had a check on the forums to make sure this isn't a duplicate. But I can't find another topic asking this, so here goes... Everyone seems to have a different story on how they became a brony. Some people were haters that decided to give the show a chance with an open mind and they liked it. Others just watched it out of curiosity. So how did you become a brony?
One day when I was watching tv, I saw an advert for mlp fim (I live in England so this was around July 2011) but I didn't really think anything of it and just brushed it off. A few days later when I was channel flicking, I got about a 5 second glimpse of the show (from applebuck season I believe) where Applejack jumped onto the plank and sent Rainbow Dash flying into the air. It made me chuckle and so I decided to look up the show on youtube. I watched a few of Kryospawn's short clips and after watching a few of them, I see PONIES: The anthology as a related video.
After watching that, I watched the entire first season in a weekend and have happily been a brony ever since.
