The TV rental business was very much like mobile phone contracts. For this reason I am not one of those people that buys a mobile phone on contract with the 'upgrade' every two years. The 'contract' your family were on for the TV was 'pay as you go' and I shudder to think how often your family could have paid for the TV, probably ten times over!
The fear of the TV detector van kept people tuned in to what important stuff was being disseminated on the state broadcaster that pretends to be independent. Sure there were home computers, VHS/Betamax and 'the wireless' back then but screen based entertainment was limited.
The TV had four channels (if you were lucky), so that meant news every night about the latest Cold War tensions, the misery of the Miner's Strike, the joy of the Poll Tax riots, the obsession with inflation, the latest dole figures, what privatisation was being flogged, 'Protect and Survive' and messages about how heroin screws you up.
Remember there was no such thing as society, you just had to hide behind your door and rely on the 'neighbourhood watch' signs for security. Crime really was a thing then, burglary a fear far worse than it should have been. The BBC very much reflected this but we remember 'Life on Earth' and tell ourselves how wonderful the BBC was.
Icing on the cake for this miserable era was the actual BBC. Radio 1 was 'Smashy and nicey' DJs that were quite depressing and BBC children's programming had presenters that have invariably been prosecuted in recent years for child abuse related offences.
But at least we had a national conversation. Remember 'who shot JR?'. Nowadays people would be saving the box set to watch later so you can't have this shared conversation, if anything it is anything but.
