Forget SOPA. The biggest online intellectual property story last week was the shutdown of a website offering downloads of the cartoon My Little Pony: Friendship is Magic, which shook the burgeoning "brony" community to its core.
Bronies (bro+pony) are adult male fans of the new series launched in 2010 based on the classic ‘80s My Little Pony toy that [spoiler] your mom secretly threw out your collection of when you went to college.
If you think bronyism sounds like something only a serious pervert living in his mother's basement would be into, you're only about 30% correct. To address your immediate question: it's not ironic. It's nerdy guys who genuinely enjoy an animated series about ponies. The show has a legitimate appeal to older audiences—high production values, snappy dialog, and a heartwarming message. But the online fan culture of bronies grew out of 4chan, so they have a computer nerd vestigial tail of Mountain Dew, anime appreciation, chronic virginity, and cyberbullying.
Bronies have their own news sites, fan forums, and even a healthy amount of fan art of ponies doing unspeakable sexual acts on Tumblr. They've had real life meet-ups, and an upcoming BronyCon in New York will feature appearances by voice actors from the show.
