The first registered ccTLDs were .us, .uk, and .il, all registered in 1985.

org.org domain
Most registrants in the United States of America have registered for .com, .net, .org and other gTLDs, instead of .us, which has primarily been used by state and local governments, even though private entities may also register .us domains.
The domain ".org" was one of the original top-level domains, with com, us, edu, gov, mil and net, established in January 1985.

Domain hack

domain hacksdomain hackingopportunistic
One of the first .us domain hacks, icio.us, was registered on May 3, 2002, for the creation of the subdomain del.icio.us.
For example, blo.gs makes use of the ccTLD .gs (South Georgia and the South Sandwich Islands) to spell "blogs", fa.st makes use of the ccTLD .st (São Tomé and Príncipe) to spell "fast", every.one uses the .one gTLD to spell "everyone", Instagr.am makes use of the ccTLD .am (Armenia) to spell the name of photo-sharing service "Instagram", helpmelearn.it makes use of the ccTLD .it (Italy) to spell "help me learn it", sexyi.am uses ccTLD .am (Armenia) and darkvir.us uses ccTLD .us (United States) and sharing it for subdomains with free hosting, tel.ly uses ccTLD .ly (Libya) to spell "telly" (a popular British colloquial term for television), and some of Danbooru-style imageboards that end their name with '-booru' suffix may use the ccTLD .ru (Russia) to spell their own name.
