    What does it mean to be "sponsored by Stack Overflow for Teams", when the whole network is owned and operated by Stack Overflow? I thought SO for Teams was just part of the SO company. – Rand al'Thor Jan 6 at 12:28

    Are you posting this from your knowledge, or is there a general way to find out? – SouravGhosh Jan 6 at 12:34
  • @SouravGhosh there is no general way to find out (so I could have missed one or two, but I doubt it). – Glorfindel Jan 6 at 12:35
  • Kind of on the line for what you seem to be asking, but Lego offered WB2019 prizes, has prominent placement on the site, and gives prizes to the users; I don't think they pay SE anything (money, or Lego) - so I'll let you decide to edit it in as an answer, or categorize it as a special sponsor: bricks.meta.stackexchange.com/questions/367/… bricks.meta.stackexchange.com/questions/198/… – Rob Jan 6 at 13:21
  • @Rob I just meant official site sponsorship. It's also possible to sponsor tags (mostly used on Stack Overflow). Sponsorship of contests might be interesting as well, and there must have been more in the past, e.g. apptivate.ms. – Glorfindel Jan 6 at 13:43

    Glorfindel, according to RC's definition what amounts to "sponsorship" in SE's eyes is fairly open. Another example is AskUbuntu which has no "sponsored by" banner on their site. I just tried Googling stackexchange.com "sponsored by" and found that new info - you might want to pursue that search beyond the first few hits, I only spent a few minutes looking. – Rob Jan 6 at 14:27
