The government of Tonga sells domains in its ccTLD to any interested party. The .to ccTLD is administered by the Tonga Network Information Center (Tonic).
The .to top-level domain was widely commercialized in 1997 by the San Francisco company Tonic Corp. (www.tonic.to, founded by Eric Gullichsen and Eric Lyons) which would sell domains at $100 per unit. They operated with the approval of the Prince of Tonga. Network Solutions was already selling .to domains, but in a very chaotic fashion. Domain requests were processed by the Tongan consulate in San Francisco.
The top-level domain to itself had an A record and a HTTP server since at least 1998.
Because to is a common English preposition, it became popular to craft memorable URLs called domain hacks that take advantage of this; URL shortening/redirection services (e.g. go.to) are a popular use. Other domain hacks do not use the to as a preposition but rather as a syllable inside of a word, including Daniel J. Bernstein's website cr.yp.to, London web development company Potato p.ota.to, and uploading services such as uloz.to (which means "save it" in Czech and Slovak).
"T.O." (tee-oh) is also a common nickname for Toronto, Ontario, Canada, and is used as a city domain as exemplified by popular Toronto sites Budtender.to (Cannabis Dispensary Reviews) and Jobs.to (Job Bank Toronto). This domain is also used for the city of Torino (Turin), Italy, and also as a domain hack in Slavic languages (to meaning it).
As the .to domains are purchased, all normal DNS operations are possible and registered sites are not required to display ads on behalf of the registrar. Some domains are free, like .edu.to, but only to real Tongan educational institutions. At this moment businesses registered in Tonga can also get free domains. People who sell on .to domains can claim a commission.
.to is one of the few ccTLDs that (officially) do not maintain a (public) WHOIS database providing registrant information. It is possible to contact domain registrants via tonic.to by typing the domain in the domain search field under "New Domain Name".
