My Little Pony is an entertainment franchise developed by Hasbro which is marketed primarily to girls. Started as plastic pony toys developed by Bonnie Zacherle, Charles Muenchinger and Steve D'Aguanno which was produced since 1983, the ponies feature colorful bodies and manes and a unique symbol on one or both sides of their flanks, referred to in the two most recent generations as "cutie marks." My Little Pony was revamped at least four times with new and more modern looks to appeal to a new market.
