We had "Tyne Colour" tvs at school (in Essex), the ones with wooden doors, and a speaker that looked like a bar of chocolate. Can't find a picture of one on the internet, unfortunately 😭 By the mid-80s we had ordinary Ferguson tvs...no more doors! Geography, and sometimes Biology, was the only subject we got to watch tv. Junior school was a bit more varied..."How we used to live" (WW2) was pretty good. And some drama type thing about a peregrine falcon and egg thieves! And some music programme too. Good times 🙂
