did UK TV's ever have coin slots on them?

A co-worker who's husband grew up in the UK is telling us that TV's back in the day had a coin slot on the TV and you put change in to watch a show. Because of this there was no cable bill like we have in the US.
True or BS? I already looked on google for any images of a TV with a coin slot and didn't see anything.
You may want to turn 'safe search' on before doing an image search for "coin slot" though
