I want to know, how many top-level domains (TLDs) are currently owned by Stack Overflow?

As I know there is only stackoverflow.com. Are there any other TLDs owned by Stack Overflow?

stackoverflow.com is owned by Stack Exchange, not by "stackoverflow".

It also owns:

  • answerama.com
  • apptivate.ms
  • arqade.com
  • askdifferent.com
  • askpatents.com
  • askubuntu.com
  • basicallymoney.com
  • blogoverflow.com
  • chiphacker.com
  • crossvalidated.com
  • hatdash.com
  • me3missions.com
  • nothingtoinstall.com
  • s.tk
  • seasonedadvice.com
  • skyrimvsmw3.com
  • serverfault.com
  • sstatic.net
  • stackapps.com
  • stackauth.com
  • stackexchange.com
  • superuser.com
  • winterba.sh

And probably some more.

  • Note: Stack Exchange, Inc. now does business under the name Stack Overflow.

  • I've edited a list of Stack Overflow domains in a different answer to include stackoverflow.co. Any objections to my editing it into this answer? It's used for the data request URL (policies.stackoverflow.co/data-request)

Stack Exchange don't own any TLDs.

stackoverflow.com is a domain. It's not a TLD; a TLD is a Top-Level Domain, such as .com and .uk

Of the Stack Exchange domains, there is at least these:

  • How has the domain s.tk been registered? I thought the minimum length of a domain name (minus TLD) was two characters. Also, a whois search for s.tk returns me "Invalid output"

  • @caiosm1005 - That's up to each TLD's manager. x.com is valid, for instance, but no new one-letter .coms are being created.

    Surely Oded doesn't need the reputation, but this still bothers me. Why repeating an earlier answer?

    @Arjan I guess the aim here on meta, as elsewhere on StackExchange, is to create a single, best, definitive answer, which can then be accepted; and that can mean merging bits from other answers too. I think I've understood that right, but please correct me if I'm wrong

    Sure, that's the aim. But there are things like attribution. You saw my answer and thought to use it - fine. Could have added something about that fact.

    Like @Oded, I disagree here, but even think attribution was not good enough here. Changing a useless answer (your first revision was useless, I feel) into a good answer by copying someone else's answer (which also was older) smells VERY bad to me. You should just have deleted your answer, I feel.
