The .blue domain was applied for by Afilias under ICANN's New gTLD Program. Despite a Legal Rights Objection from Blue Cross and Blue Shield Association, the objection was dismissed in August 2013. Afilias signed the registry agreement with ICANN on November 7, 2013, and .blue was delegated to the DNS root zone on February 5, 2014. Responsibility for the TLD was later transferred to Identity Digital Limited, which now operates the registry.
