Does anyone have the data?

Jan Velerop noted:

"I estimate the industrial revenues in respect of primary journals to be
less than 5%."

JE:  I think this is a responsible, educated estimate, but I wonder (and
have been wondering for years) if anyone has the data. In publishers'
parlance, this is called a "sales-by-channel" analysis.  Every individual
publisher tracks this in great detail for his or her own publications, but
channel proportions vary by journal, by discipline, and by geography
(e.g., for hardcover books, bookstores in France have greater market share
than bookstores in the U.S.).  One of the reasons that the information is
hard to come by is that publishers guard it zealously, as I always did and
do. Another reason is that publishers use different typologies; one man's
government account is another man's institutional account.  This is also
expensive market research to do, if done well (probably a $50k job in the
U.S. alone, maybe a bit more).

I would love to see this data.  Ideas, anyone?
