.tv is the Internet country code top-level domain (ccTLD) for the island nation of Tuvalu. Except for reserved names like .com.tv, .net.tv, .org.tv and others, any person in the world can register a .tv domain for a fee, much of the income from which goes to the government and people of Tuvalu. The domain name is popular (and thus economically valuable) due to it being an abbreviation of the word 'television' (other similar ccTLDs are .fm, .am, .cd and .dj). Domain names used in this manner are known as domain hacks. The domain is currently operated by The .tv Corporation, a VeriSign company.

There has been some controversy as to who should be allowed to reserve .tv domain names. A significant percentage of websites with .tv URLs are pornographic or otherwise sexually explicit. While this has raised significant revenue for the small nation, it has also created conflict. Much of Tuvalu's population is conservative Christian, and some feel that revenue from those sources is immoral.

The Tuvalu government Web site is implemented as a wiki using the TikiWiki software.
