Default Odd resistors identification

Does any one know the origin of this way of marking resistors and when
it was abandoned?

It was based on the Roman numeral "M" representing 1,000, but I don't
know when it stopped being used.

I still see "M" being used to represent thousands of dollars, and MCF is
still a pretty standard representation of "thousand cubic feet" of
natural gas.
