here's why the 45 singles' hole is the 45 single hole size
That's a really nice article, btw ... and very historical ... and you can even get more and other ideas by watching Tom Dowd's DVD, who used to cut the disks directly into the platter, or master ... right after WW2 ... and his history of music in America all the way to the late 60's is second to none. In many ways, it is more important than George Martin's.
Sadly, Tom will never get the credit he deserves ... for the unbelievable historical document that shows more about music in the 50's and 60's in America than anything else ... but something that most people are still way too segregated and not appreciative of.
I can easily say, however, that in music TODAY, at the very least, is the one place where ... most folks do not give a darn about anyone's color ... all that matters ... is ... play man ... play! But it was not like that for a long time!
