The Top Level Domain has in such cases not the original meaning: .tv stands for Television, not for Tuvalu.
A domain hack has nothing to do with hacking a domain or website. The "hack" represents a trick (as in programming), not an exploit or break-in (as in security).
Domains such .as .it, .me ,.to, .is and .us are easy to use as domain hacks as they correspond to short, simple dictionary words. Sometimes a name is chosen so that the last few characters match an existing top-level domain, such as "inter.net", so that every character is used in forming the common name.
You can select many Top Level domains for a domain hack.
The favorite domains are:
The Serbian domain .rs fits also, as many English words have "rs" at the end.
