.io
Tech startup ending
A top-level domain originally assigned to the British Indian Ocean Territory but now widely used by technology companies and startups, where "io" suggests input/output—a computing term.
The extension has become shorthand for tech products and services: The new app launched at sketch.io.
Gaming sites also favor .io for simple browser games: agar.io, slither.io.
