Incorrect. CBS owned and operated a tv and radio manufacturing arm, acquired Fender musical instruments and rolled their separate manufacturing arm under the Fender design name. They bought toy companies, the X-Acto knife company, all again making stuff while owned wholly by CBS.
CBS even had its own R&D lab which ran for 50 years, again killed in the 80s, including development of military tech.
Then in the 80s the divestment era hit wall st and everything was sold off, including the company itself in the 90s.
Which fast and furious plot line was this again?
