I should have made myself clearer, I guess. Yes, the original "EP" was
for multi-track 45's. If I remember correctly, Columbia may have started
that (although RCA invented the 45). I think Columbia also used the "LP"
on their 33 1/3 discs. 

As David said, the "system" got bastardized. At one time or other all
speeds have been used on all size discs. Like I said some time back,
They even made discs with inside start (frustrating if you put one on
a changer). The old Edison discs that were about 1/4 inch thick were
"microgroove" and had vertically modulated grooves to increase playing
time.
