About .boo

.boo is a generic top-level domain (gTLD) made for Halloween, ghosts, and spooky fun, but its real purpose is broader than just a boo. It is operated by Charleston Road Registry Inc., a Google subsidiary. There are no strict eligibility rules, so anyone can register a .boo domain for personal or business use, whether for a horror fan site, a haunted house attraction, or a playful brand. The domain was delegated on August 28, 2014, and the registry runs on Google's backend infrastructure.
