By 1977, the dual-running of 405-line VHF in monochrome and 625-line UHF in colour has contrived to cover almost the entire country, with reception now available to over 97% of the population, including all but a few tiny pockets in Scotland and Wales.
The network has changed radically, with the ending of the chronological split of the major regions except London and the handing over, in 1974, of Belmont in Lincolnshire to YTV from Anglia.
The Midlands, thanks to UHF, now covers much more of the east. London is now much more restrained and would be more so again 20 years later.
