Teenage Mutant Ninja Turtles is an entertainment franchise created by American comic book authors
Kevin Eastman and
Peter Laird. It follows
Leonardo,
Raphael,
Donatello and
Michelangelo, four
anthropomorphic turtle brothers trained in
ninjitsu who fight evil in New York City.
Eastman and Laird conceived the characters as a parody of elements popular in
superhero comics at the time. In 1984, they founded
Mirage Studios and self-published the first issue of
Teenage Mutant Ninja Turtles; it was a surprise success. They licensed the characters to
Playmates Toys, who developed a
line of Turtles action figures. About $1.1 billion USD of
Turtles toys were sold between 1988 and 1992, making them the third-bestselling toy figures ever at the time.
The action figures were promoted with an
animated series, which premiered in 1987 and ran for almost a decade. In some European regions, the word "ninja" in the name was replaced with "hero" for its violent connotations. Three live-action films were released in the 1990s; the
first film became the highest-grossing
independent film up to that point. In 2009, the franchise was purchased by
Viacom, now
Paramount Global. Viacom commissioned a
new comic series, two new live-action films, and new animated series.
