W and K prefixes.

I'll stand to corrected but my recollection is that a further partition
existed within the USA in the 50s and earlier.

W was issued to stations, at least commercial stations, East of the
Mississippi and K was issued to station west of the Mississippi!!

Any confirmation????

Hi,

I am currently writing a long article about the history of ham radio for my
website (growing...).
Can someone tell me who :
- What committee or association assigned the first prefix to callsigns in
the middle of 1920's, ITC (future ITU) ?
- On what base (I suppose location) US stations were assigned A, K, N or W
letters and who decided for the other countries ?
- Who currently manage these prefixes at a worldwide scale ? ITU-R (ex CCIR)
?

Thanks in advance
