A little story:
In 90s, there was a boom of video gaming consoles (8bit NES\Famicom bootlegs called 'Dendy'), and most of us kids were playing it on old soviet TVs. There were modern Japanese TVs in most families but our parents were confident, for some reason, that console will spoil CRT. So they gave us their old (often black-and-white!) TVs for gaming. I lived in rural Siberian village, but as I learned later it was the same nationwide.
The point is, those old TVs were from 70-80s and many families had more than one.
