>2011 to 2014The /co/ is love era. Bronies are created and then exiled. Proto-culture war/pre-gamergate tensions begin to flare up. /co/mblr is coined around this time
>2015 to 2016Transitional period and a calm before the storm. Herny was still active, Zoot Suit Tom/Literally Me Daffy begin to really take off. Samurai Jack is announced. There's some renewed hope around this time. Some shitflinging and tumblr carryover but otherwise peaceful.
>2017 to current/co/ can't decide between being /co/mblr or a /pol/ battleground.
