15 November 2013 Last updated at 00:03 GMT
It is a TV show about cartoon horses made for little girls.
Yet in just three years, My Little Pony: Friendship is Magic, produced by Hasbro Studios, has amassed a huge following among an unlikely audience - grown men.
They call themselves Bronies.
The appeal lies in stories with a moral outlook, the animation and the humour.
A huge culture of music, art and remixed versions of the show has now spread globally on the internet.
