The TV listings in many of the newspapers used to use the region names for ITV apart from “Midlands” and “London” - I believe this was still the case well into the 90s. I assume it was originally done that way to avoid having to name two companies (ATV/ABC and Rediffusion/ATV etc) and/or to avoid the confusion of ABC North and ABC Midlands. I expect that prior to 1968 the newspaper listings also referred to a “North” region (Granada/ABC) - but it seems strange that “Midlands” remained 20 or so years after the weekday/weekend split was abolished, and the company name had changed too.
