True, digital PLL sync meant that the signal was much less likely to drift, but it was still possible. I definitely had a TV with a vertical sync control right up to the early 2000's (though it was NTSC rather than PAL so a generally inferior system).
Ah - NTSC = never twice same colour. The American system, which, for all its faults, did see widespread colour TV use a decade before the Europeans managed it......
Going back to things you don't see any more in people's houses - how about hard, shiny toilet paper and one of those knitted dolls which covered the spare toilet roll ?
