This is a video about the Format War of 1949. Things like 12″ 45s, 45 RPM Albums, EPs, 16rpm records, Polystyrene singles and 45s with a raised stepped ridge around the centre that aids grip when stacked don’t feature in this story because they were introduced after the conclusion of this particular story.
Regarding the question posed at the end – a few people have mentioned that the record players in their country had single adaptors. This was not unusual. I’ve demonstrated a few turntables on this channel with the built-in 45 adaptors. If your turntable didn’t have a built in adaptor – you could buy one. However that’s the result – not the cause. The records came first – the players accommodated the type of records sold in that country. A country could have chosen to go with small or large holes – the decision on which way they went was the thing of interest – what was the common denominator? Why was a large spindle hole chosen in Germany, but a small one in the UK?
We think we have an answer – it seems that Commonwealth countries went with the small hole and countries with a US armed forces presence after the war were more inclined towards the large hole. However if you know any other info on this – please share.
