The Teenage Mutant Ninja Turtles (or simply Ninja Turtles, and previously known in the United Kingdom as Teenage Mutant Hero Turtles) are a fictional team of four turtle mutants, who are trained by their sensei, Master Splinter, to become skilled Ninja warriors. From their home in the sewers of Manhattan, they battle petty criminals, evil megalomaniacs, and alien invaders, all while remaining isolated from society at large. The characters also initially appeared in comic books before being licensed for toys, cartoons and film adaptations.
The Teenage Mutant Ninja Turtles originated in an American comic book published by Mirage Studios in 1984. The concept arose from a humorous drawing sketched out by Kevin Eastman during a casual evening of brainstorming with his friend Peter Laird. Using money from a tax refund together with a loan from Eastman's uncle, the young artists self-published a single issue comic intended to parody four of the most popular comics of the early 1980s: Marvel Comics' Daredevil and New Mutants, Dave Sim's Cerebus and Frank Miller's Ronin.
Much of the Turtles' mainstream success is owed to a licensing agent, Mark Freedman, who sought out Eastman and Laird to propose wider merchandising opportunities for the offbeat property. In 1986, Dark Horse Miniatures produced a set of 15 mm lead figurines. In January 1988, they visited the offices of Playmates Toys Inc, a small California toy company who wished to expand into the action figure market. Accompanied by the popular Teenage Mutant Ninja Turtles 1987 TV series, the TMNT were soon catapulted into pop culture history. At the height of the frenzy, in the late 1980s and early 1990s, the Turtles' likenesses could be found on a wide range of children's merchandise, from PEZ dispensers to skateboards, breakfast cereal, toothpaste, school supplies and cameras. The original cartoon series was featured on VH1's I Love The 80's and the toys based upon the show were ranked 33 in I Love Toys.
