The My Little Pony series of minidolls combined young girls' fascination of horses with two elements of doll play successful since the days before Barbie: hair care and fashion. Each pony sported a long silky mane and tail in pretty pastels and its own comb for grooming. Additional outfits (leggings and shoes, four to a package of course) and accessories rounded out the props of play. Introduced in 1983, My Little Pony produced characters each year thereafter. By 1990, more than 100 million dolls in the line had been sold. The line has stayed in production nearly continuously since the 1980s. Recent versions of My Little Pony, begun with the launch of the 2010 TV series "My Little Pony: Friendship Is Magic," attracted not just young girls about also an adult following. To celebrate the 30th anniversary of the line, in 2013 Hasbro introduced Equestria, the characters of the "Friendship Is Magic" imagined as very unhorse-like teenaged human girls.
