The Technology Connections video series on RCA's Selectavision CED home video system touches on this quite a lot (it was a horribly mismanaged project which took more than a decade to commercialize, by which time it had already been superceded by VHS/Betamax and Laserdisc)[1]. His main source for the information on the development of the CED system was the book "The Business of Research: RCA and the VideoDisc" by Margaret B. W. Graham.
