Y'know, it's interesting how remarkably universal deployment of technology was in high-income, spacious countries (i.e. Scandinavia/North America/Australia) was in the '70s....other than style, really little separated these (very slightly aspirational) views of suburban life from a similar US or Canada P&G ad from the same year. I remember going to an automotive styling exhibition in Stockholm 20 or so years ago and observing the similarities in Northern Europe auto culture to US auto culture...local cars (Volvo/Saab) were quite large compared to southern Europe cars...people were big, cars were big, houses were big.
About 15 years ago, there was an interesting article in either the Wall Street Journal or one of the other US business magazines talking about the consolidation the appliance manufacturing in Europe, and stressing how different country-by-country range designs were (as you see here, huge US-scaled stoves in Scandinavia; smaller stoves in the UK with weird side-wall heating elements, etc etc etc).
