If you do find it, please do post it so we can keep track.

Correct, both authorized and unauthorized are all either GOG or Steam keys, any GOG keys would be GOG customers upon redemption (whether bought or free etc.), but presumably those keys are not counted until they are redeemed.

Yeah, at the present the figures we have to work with are pretty vague or dated at best with reasonable sized margin of error which would get compounded with each additional data point used in estimation thus lowering the accuracy of the resulting estimate, but it would just mean that you end up with a range rather than a specific number, and the width of the range would be a reflection of the quality of data used in estimation.

I went through CDP's quarterly/annual reports and while they contain profitability figures and other really interesting data, none of it could easily translate into numbers that are terribly useful for estimating the size of the GOG customer base as I had hoped. :/

Still, I think it's safe to say they have millions of Witcher 3 customers here on GOG and that they only account for a fraction of the total customer base, and while we can't draw a conclusion - it is reasonable to estimate a similar percentage of ownership of the game compared to Steam if we can get decent numbers on Steam. I found some stuff but it's hard to find updated figures on Steam and on Witcher 3 sales, and the recent GOTY release only further complicates that with little info available. :/

not the one I was looking for:

A beta version of GOG.com was launched in 2008 with a few titles available from Interplay, the site’s first partner. The 2-year beta saw the signing of over 100 partners including big publishers and independent studios. GOG.com released nearly 500 classic games, reaching over 1.7 million gamers per month.

Then, in 2011 the site launched its first new title: CD Projekt RED’s The Witcher 2, which sold 40,000 copies through GOG.com in its first three months. Valve’s much larger Steam platform sold 200,000 in the same time frame, but CDP viewed the event as a massive success.

Crap, I can't read anything on Forbes because I use an ad blocker I refuse to disable for any reason and they say "screw you" to ad blockers so... :)

Going by your quoted data though it seems that they had 1.7 gamers back in 2008, and it is 8 years later and the site has sustained rather enormous growth in title quantity, platform availability, wider appeal (newer games, some AAA, indie trends, etc.), and Galaxy and its features, plus the flagship products. If that 1.7M gamers per month means sustaining that number, it has likely grown significantly since then for sure.

There are at least two different numbers that would be nice to have though, and that's total number of accounts that have made at least one actual purchase, and also total revolving active accounts over time. The former number is likely much higher. Best stats I could find for Steam were 125M accounts, 8.9M average active.

people with many ideas are called idiots :-/

That's why I pasted it here as well.

OK, I found (sorry German) Steam with 10 Million daily active users and they upgraded their hardware.

DOn't reply yet, still digging ;)

Over 140 million customers (from August this year this number

There was a website on which you were able to look up the owner and as well the value of a website, damned, too long ago that I used it, it was also reporting daily hits......
