Billy, allegedly the 45 was invented from 78-33 = 45, (the RCA vs EMI / Columbia patents ) although I have also heard that the speeds were derived something from electrical motor phasings.

Releases probably depended on on pressing plant avaliblity. By the mid 50s I would guess new speed record players were becoming more common, so logically a 45 might come first, but I guess small labels knew their markets and where & when best to distribute different formats.
