I encounter no ads that I am aware of, and it must cost money, which makes me wonder.

    $\begingroup$ That's strange; I get sometimes ads of mathematica, sage and others below or above the "community bulletin". Surprisingly it is sporadic; but even more surprisingly it occurs although I have adblock+ active and the ads pages at stackexchange are blocked. (This is really harassing me, btw, they must have a special fancy js-function to neutralize adblock) $\endgroup$ Nov 16, 2012 at 9:09
  • $\begingroup$ actually, they come initially from i.imgurl.com, and when you move the mouse over them, they "change their adress" (???) to some "meta.math.ads.*", and if you reload the page, adblock+ seems to be able to block them then. It is really distracting the concentration from the reading of the math-contents of the questions... $\endgroup$ Nov 16, 2012 at 9:20

    $\begingroup$ @GottfriedHelms Those are the Community Promotion ads that are chosen and created by the community itself. Additionally there are in-house ads for other sites in the network. $\endgroup$

Stack Exchange is earning money by ads on the three largest sites (Stackoverflow, Superuser and Serverfault) as well as their Careers platform.

None of the SE 2.0 sites like Math earn any money at the moment.

please ignore this answer [see the comments below]

I have seen ads here and actually of products that I found useful, unlike the rest of the web.
