I remember when my parents first got a colour TV, in the early '80s, I think? (For that matter, I can remember, just about, when we first got a TV at all).
In fact the last TV I had (up till about 20 years ago, around the time the internet seemed to take away most of the purpose of having one) was B&W (because the licence was cheaper! The main expense of a TV now is the licence, rather than the 'hardware'...the BBC may be unsustainable for that reason...funny thing really that the BBC came into existence in the first place because the radio-manufacturers needed someone to produce content so they could sell radios - now it's the content that costs you, the hardware is a minor part of the cost).
Pity I can't get the internet in Black & White and save some money on that.
