Simply put: Lauren Faust took the My Little Pony franchise, which was for years the stereotypically "girly, fru-fru" show, and turned it into My Little Pony: Friendship Is Magic. In the process, she managed to create an enormous Periphery Demographic of adult men and women, and astound viewers the world over by just how good it was. Now that is impressive.
Even better? The president of Cartoon Network refused to let her make any shows with female main characters because he thought no one would watch them. Her outstanding success may explain why CN is letting her make a cartoon with an all female cast.
