Nearly 200 million dotcom domain names have been registered since 1985.
Symbolics added dotcom to its name on March 15 1985, followed by Bbn.com and Think.com, at a time when the market was small and dominated by computer companies.
Only six dotcom names registered in 1985, compared to 10,000 registered daily today.
Symbolics registered the first .com with domain registration Network Solutions, which was acquired by Verisign in 2000.
Symbolics, a computer systems and software maker, was purchased by XF.com in 2009 and the domain now serves as the XF.com blog.
Nominet, the national registry for .uk internet domain names, is currently reviewing its rules on the registration of one character or two letter domain names.
Brands that could register a new domain name include the AA, BA, 3 and MG.
