Here is an interesting story on the corporate history of Philco-Ford (the story is at the bottom of the page)

Also, only the consumer products division of Magnavox was sold to Philips. The orginal company continued as a govt. contractor in Fort Wayne, still using the original upper and lower case Magnavox logo, until 1995, when it was purchased by Hughes Aircraft.
