History of the TLD

The .icu domain is a generic top-level domain (gTLD) introduced through ICANN’s New gTLD Program to expand the domain name system with versatile namespace options. It was delegated into the global DNS Root Zone in 2015 and entered general availability in 2018. The name “ICU” is interpreted as “I See You,” reflecting a branding concept centred on visibility and connection online.

Main Use and Industry Position

.ICU is positioned as a global, unrestricted domain extension suitable for individuals, organisations, and businesses across all industries. It is used for personal branding, startups, creative projects, event sites, portfolios, and general web presence. Its affordability and high name availability make it attractive for users seeking alternatives to traditional extensions such as .com or .net.

Comparison to Other TLDs

Compared to legacy TLDs like .com, .net, and .org, .icu provides broader name availability at lower price points. Unlike restricted sponsored TLDs (.edu, .gov) or geographic ccTLDs (.au, .uk), .icu does not impose eligibility requirements. Relative to other new gTLDs (.xyz, .online, .tech), .icu’s branding emphasis on “visibility” distinguishes it in marketing narratives, though its adoption level varies by audience and region.
