Task: Question Generation
Input (English): Government revenues largely come from sales of fishing licenses, income from the Tuvalu Trust Fund, and from the lease of its highly fortuitous .tv Internet Top Level Domain (TLD). In 1998, Tuvalu began deriving revenue from the use of its area code for premium-rate telephone numbers and from the commercialisation of its ".tv" Internet domain name, which is now managed by Verisign until 2021. The ".tv" domain name generates around $2.2 million each year from royalties, which is about ten per cent of the government's total revenue. Domain name income paid most of the cost of paving the streets of Funafuti and installing street lighting in mid-2002. Tuvalu also generates income from stamps by the Tuvalu Philatelic Bureau and income from the Tuvalu Ship Registry.
Output (English): What company is managing Tuvalu's tv domain?
