Princess Cadance: Cadance just kind of glosses over that and looks at Shining. "Uh, honey? Have you refreshed the barrier yet?"
Shining Armor: Oh, yeah, heh heh... should probably do that. Right, I didn't mention that thing ponies get, did I? The, umm...
DM: Cutie mark?
Shining Armor: Yeah, that.
DM: Wait, isn't your GM using parts of my homebrew? This isn't your first pony character.
Princess Cadance: Haha, don't pretend like you're too manly to know about cutie marks.
Shining Armor: Hahahaha! Alright alright, yeah, my cutie mark is a shield with stars. And that shield means that my special talent...
Rarity: *You're* the one casting the barrier spell? The giant one covering all of Canterlot?!
Shining Armor: Yep. Kind of a Very Important Pony here.
DM: The benefits and responsibilities of being a one-shot character.
I started watching before I even started using internet forums so I don't even know when the community sprang up.
I think I started watching around the beginning of season 2. I remember because they were doing a marathon of all the episodes up to the return of harmony.
I found out about the show between seasons 1 and 2, and I found out about if from members of the community.
Original artifacts from the /mlp/ era are sporadic nearly a decade later, but off the top of my head I can point to both Cupcakes and Equestria Daily as dating back to January 2011 (although I doubt one would have much luck tracking down the original posting of Cupcakes). I do know of one older fanfic, Severance (also grimdark), though I don't know how much older it is.
Newbiespud, no offense meant as I know you didn't mean it negatively and more as a "the fans managed to make others see men liking colorful ponies as more acceptable" way, but the way you phrased that makes it sounds like "the brony fandom is about making men feel ok about the fact they're enjoying a girl's show about colorful ponies."
The choice of words "primary function" was intended as a bit of comedic hyperbole, unclear as it is. Sorry. Just meant to point out that that was arguably the fandom's biggest hurdle back in the day.
Can't get it... in the world the show FiM does not exist. So no fandom, and no ponies with cutie marks. Or do earlier generations exist here? That explains, if so,
I blame Derpy.
Someone was exclaiming about how they brought her back (dropping things on Twilight).
I figured I'd check out the clip... okay, that's actually funny. Let's go ahead and.. no, wait, I'll want context, first episode... Hey, this is pretty good. Okay, now can watch that one... annnd I'm hooked, aren't I?
...Am I the only one here who was lured into watching the show by the, um... Archetypal side of the furry fandom? Fluttershy-chan wa sou kawaii desu... As for when, pre-S2, not sure exactly how early, but...
It was my Spanish Reenactment buddy got me into it. He goes "I promise you'll like it." And I goes "Really???" And he goes "I give you my word as a Spaniard!" to which I retort "It's no good. I've known too many Spaniards." then he got all serious and was like "I swear on the life of my father, Domingo Montoya, You will enjoy this show." And well, there was only one thing to say. "Send me the link."
There was a Pathfinder Campaign a buddy was running that I was supposed to be offshore for most of, so he basically gave me carte blanche for Character Design. I made a Young White Dragon with class levels in Slayer. The party wound up calling him Toby.
He was... mildly broken. Like, 300' charge radius, five natural attacks with his lowest attack bonus being a +20 (We were level 14 at the time) and his BAD saves being +10 or so.
Mind you, it worked out because that particular GM had decided our games hadn't been challenging enough lately, and Toby is the only reason he didn't TPK us on multiple occasions.
I remember first noticing the newly forming fandom around the time Bridle Gossip aired. A lot of screencaps from Pinkie Pie's little song started cropping up all over DeviantArt at the time.
Funny thing is I didn't actually connect it to My Little Pony at the time. Since the design style was so different than what I knew of the franchise. So my first thought was "whatever that is, it's apparently popular."
Then season 1 appeared on Netflix and I went "wait what?" Finally got curious enough because of the show's apparent popularity to start watching it a week later, and caught up around the time MMMystery on the Friendship Express first aired.
Don't quite remember when I started becoming active in the fandom though. I know it was related to discovering Legends of Equestria and EQD, but I can't put a date to it.
