I believe Gottlieb was sold to Colombia Pictures at about 1979, by D Gottlieb.  I think it was CocaCola that then bought Colombia Pictures in about 82, that they changed the name to Mylstar, and started changing the companies direction.  Mylstar then closed up (sounds like 84), only to have some former employees buy up the stock and factory equipment, and start a new company called Premier.

Premier then closed up in the mid 90s.


...David Gottlieb sold the company at its peak, when pinball was earning more revenue (cash box earnings?) than the movie industry.  The David Gottlieb sale would be one of the best business moves of the century.
