Arnold Greenberg is an American businessman (born c. 1934) best known as the CEO of Coleco in the 1970s and 1980s. He began his career in law but joined Coleco, a family toy business, in 1966. He worked aggressively to gain a large share of the video game market while maintaining Coleco's position as a manufacturer of other toys. Greenberg's drive to develop and market the Adam Computer in 1982 and 1983 eventually led the company into bankruptcy.[1][2]
