For anyone who has not already see it, there is a fascinating film on Youtube about the early days of UHF in the US called "Fog over Portland".

It's marketing, thinly vailed as a documentary, and as well as addressing the suspicion the public and the trade had about UHF, the film's sponsor, Zenith, attempts to extol the virtues of its combined VHF/UHF turret tuner that would need an engineer to fit a module for any additional channel, or change of channel should the customer move to a different area, whilst rubbishing other manufactures that used a simple continuous UHF tuner that covered the entire UHF band.
