> So far without ever actually loosening things up far enough to see ads that's AT LEAST 21 different top-level domains Wired is pulling from, not counting its own (and yes, I realize it's part of Conde Nast). Most of those top-level domains have at least 2 subdomains being pulled from, sometimes more.

Nit: Those aren't top-level domains. TLDs are things like com, net, org, uk, io, etc. More info here: https://en.wikipedia.org/wiki/Top-level_domain
