The 4chan bans.
Ponies are temporarily a bannable offense on 4chan, provoking even more pony-posting and driving fans elsewhere to partake in serious discussion of the show. This caused increased traffic to other sites such as Equestria Daily and the newly-minted brony chan sites such as PonyChan. Of course, 4chan would soon welcome bronies back by introducing their very own /mlp/ board.

A silly video goes mainstream.

A new season of pony!
The first episode of season two airs. This premiere introduces a new villain character played by John de Lancie of Star Trek fame, which greatly appeals to the brony demographic. This season would go on to incorporate more fan-favorite characters and well-written stories which appeals to the grown-up fans even more.
January 21st, 2012
The 14th episode of season two aired with much fanfare from bronies. Not only did the fan-favorite character make a prominent appearance, and not only did she have her first speaking role, but she was even called by her brony-given name of "Derpy." Unfortunately, shortly after the episode aired it was censored to remove her name and "correct" her appearance. This started a widespread brony movement to #savederpy. Derpy would make a celebrated comeback in later seasons but her name would forever remain absent. Of course, everyone still knew her as lovable little Derpy.

BronyCon grows up.
The first brony event to break quadruple-digit attendance was BronyCon in Secaucus, New Jersey. The venue was filled to capacity with 4,000 bronies browsing vendors and attending panels. In order to allow even more fans through their doors, BronyCon would have to move to yet another larger location next year. While BronyCon was the largest, it's worth noting that over a dozen brony conventions took place around the world in this year alone.
