Editing Optigan (section)

==Production history==
Engineering work on the project began in 1968 and the first patents issued in 1970. The Optigan was released in 1971 by Optigan Corporation, a subsidiary of toy manufacturer [[Mattel|Mattel, Incorporated]] of [[El Segundo, California]] with the manufacturing plant located nearby in [[Compton, California]]. At least one TV commercial from the era is extant, featuring the Optigan demonstrated by actor [[Carl Betz]]<ref>[https://www.youtube.com/watch?v=MY4hyWds6Qk Commercial for Optigan circa 1971]</ref> (best known for his role as the father on ''[[The Donna Reed Show]]''). The Optigan was promoted in at least one Sears-Roebuck catalog.  All rights to the Optigan, the disc format, and all previous discs were sold in 1973 to Miner Industries of [[New York City]], an organ manufacturer who formed a subsidiary, Opsonar, to produce it. Miner had record sales for a time, in part due to Opsonar. However, sales declined shortly thereafter and production of the Optigan and its discs ceased in 1976.
