Edmark

Edmark Corporation (or simply Edmark) was a publisher of educational print materials and an educational software developer in Redmond, Washington. They developed software for Microsoft Windows and MacOS in several languages and sold it in over a dozen countries.

History
Edmark was founded in 1970 by Gordon B. Bleil by combining the assets of Educational Aids and Services Co. a small supplier of educational materials and programs and L-Tec Systems Inc. which had developed programs from its research. The Child Development and Mental Retardation Center of the University of Washington under the direction of Dr. Sidney Bijou had conducted research into the operant conditioning and reinforcement theories of B.F. Skinner as applicable to human learning. From this research, they developed academic programs which for the first time proved the viability of teaching reading to people with severe mental limitations. Bleil adapted this research into The Edmark Reading Program which for the next decade was the principal product of the company.

Bleil left the company to return to banking in 1980 and retained no interest in the company.

They began developing software in 1992. Edmark was listed on NASDAQ. Their audience was children between the ages of 2 and 16 years. Edmark had more than 65 industry design awards.

In 1989, their children, Richard, Lucy, Heather, and Chris became directors. Richard became the chairman, Heather became the CCO, Chris became the president and Lucy became the CEO in October 1989. Edmark hired former teacher Donna Stanger as vice president of product development in October 1991.

In 1992, Edmark released Millie's Math House and KidDesk. Sally Narodick resigned as CEO in September citing the stress, and Stanger became the CEO.

Edmark was acquired by IBM on November 13, 1996, for $102.3 million ($15.50 per share for two-thirds of Edmark's shares) to expand its presence in home software.

In September 2000, it was sold to Riverdeep Interactive Learning for about $85 million.

As of 2017, Houghton Mifflin Harcourt offered the Edmark, Edmark House Series, Mighty Math, and Thinkin' Things brands as licensing opportunities on its website. HMH sold the rights to many of Edmark's products to Rise Global in 2021.
