&gt; So far without ever actually loosening things up far enough to see ads that&#x27;s AT LEAST 21 different top-level domains Wired is pulling from, not counting its own (and yes, I realize it&#x27;s part of Conde Nast). Most of those top-level domains have at least 2 subdomains being pulled from, sometimes more.<p>Nit: Those aren&#x27;t top-level domains.  TLDs are things like com, net, org, uk, io, etc.  More info here: <a href="https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;Top-level_domain" rel="nofollow">https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;Top-level_domain</a>
