Stack Overflow generates revenue, how?


I would imagine that most of the revenue comes from advertising. There are adverts displayed on most pages and some tags are also sponsored.

  • OK. I'm kinda new here, but I haven't seen a single advert yet. – Jeff Jan 8 '12 at 4:34
  • That's actually what set me off looking for this question, @Jeff -- I didn't see any adverts either, and I was curious how they ran the servers without making money. – RonLugge Jul 3 '12 at 22:16
  • There is no advertising at SO. – davidkonrad Mar 6 '14 at 0:33

Some revenue comes from referral sales (sorry, don't know the exact term). Some book titles are converted to amazon links (not sure manually or automagically, though I would assume the latter). Example page is here: What is the single most influential book every programmer should read?
