Aha! Studios (formerly known as Karen Johnson Productions) was an American animation studio established in 1990 by Karen Johnson and was located in Racine, Wisconsin. It also had a unit in Toronto.
In 1995, the company expanded the business base by offering animation and related services to the computer game industry. In November 1997, Johnson received a historical tribute from Women In Animation, honoring her for her contribution to the art of animation.
The company was renamed to its current name in 2002.
