My Little Pony: Friendship Is Magic is a Canadian-American long-running children's animated fantasy television series created by Lauren Faust for Hasbro. The series is based on Hasbro's My Little Pony line of toys and animated works and is often referred to by collectors as the fourth generation ("G4") of the franchise. The series premiered on October 10, 2010, on The Hub cable channel (which was renamed as Discovery Family in late 2014). Hasbro selected animator Lauren Faust as the creative director and executive producer for the show. Faust sought to challenge the established nature of the existing My Little Pony line, creating more in-depth characters and adventurous settings; she left the series during season 2, to be replaced by Meghan McCarthy as showrunner for the remainder of the series.
