In what kind of Lalaland is 50 million nothing?

I guess parent comment is comparing facebook's quarterly revenue (~20 Billion) from ad sales, 50 million would be a fraction of a percent of 1 quarter of ad revenue I would imagine for a company like Facebook.

In the context of advertising, I read "57M" as $57,000. They would normally write 57MM if they meant $57 million, wouldn't they?

?? I would expect to see $57,000 abbreviated as $57K.

That's now how they roll in that business. CPM for instance = cost per thousand.

Maybe they all studied Latin or learned Roman numerals?

[CamperBob2]

Yep, the 'M' means 'mille' as I understand it. 'MM' is 'mille mille', or 'thousand thousand.'

Do you mean like the Roman "M" for thousand and "MM" for million? That is mixing Arabic numerals with Roman numerals.

MM to denote millions is reasonably common in some fields: https://corporatefinanceinstitute.com/resources/knowledge/ot...
