My Little Pony: Friendship is Magic

My Little Pony: Friendship is Magic is an animated series based on Hasbro's popular My Little Pony franchise. The show premiered on October 10, 2010 on Hasbro's The Hub channel, and has currently ended its fourth season. This incarnation of the franchise is referred to as the fourth generation, or G4, of My Little Pony. The show was developed for television by Lauren Faust, who is known for her work on two of Cartoon Network's popular and critically-acclaimed franchises, The Powerpuff Girls and Foster's Home for Imaginary Friends.

The series stars a unicorn pony named Twilight Sparkle, a student of Princess Celestia, the ruler of the magical land of Equestria. The princess gives Twilight the task of learning about friendship and sends her and her assistant, a baby dragon named Spike, to Ponyville. There, they meet some interesting ponies, including action-loving Rainbow Dash, glamorous Rarity, hard-working Applejack, timid Fluttershy, and hyperactive Pinkie Pie. Together, they go on adventures, solve various problems, and learn about the magic of friendship.
