.xyz is a top-level domain name. It was proposed in ICANN’s New generic top-level domain (gTLD) Program, and became available to the general public on June 2, 2014. XYZ.COM and CentralNic are the registries for the domain.
In November 2015, .xyz reached 1.5 million domain name registrations, possibly boosted in part by Google’s decision to use abc.xyz for its corporate (Alphabet Inc.) website, one of the first major corporations to use the domain.
As of January 2016, .xyz was the sixth most registered domain name on the Internet. As of June 2016, .xyz was the fourth most registered global top-level domain (gTLD) name on the Internet, after .com, .net, and .org.
Commonly used in tech.
