Dark Horse Miniatures is a miniature company formed in 1979. They moved to Idaho in 1981 and established Dark Horse Miniatures as a productive and profitable venture. In 1984, they obtained a license manufacture 25mm Teenage Mutant Ninja Turtles. The license was the first-ever granted by the TMNT creators. Sales soared, and they took on a couple of other comic book-related licenses, including Groo The Wanderer and the Robotech license from Harmony Gold. TMNT, Robotech and Groo were all successful for a couple of years. TMNT in particular sold over a million units before the license expired.
