.buick Domain Information
Passenger vehicles frame the .buick application from ICANN's 2012 New gTLD Program, one of several marque strings sought by a single automotive group in that round. Applying for a family of marque extensions rather than one corporate string was a deliberate approach: buyers shop by marque rather than by parent company, so the namespace that matters commercially is the one carrying the badge on the car.
The application did not proceed to delegation. No registry agreement was ever signed, so the extension has never existed in the DNS root zone — these were withdrawn as a group by a single automotive applicant before any agreement was reached. Strings in this position cannot be registered, and returning one to consideration would require a new ICANN application round.
