RealNames was a company founded in 1997 by Keith Teare. Its goal was to create a multilingual keyword-based naming system for the Internet that would translate keywords typed into the address bar of Microsoft's Internet Explorer web browser to Uniform Resource Identifiers, based on the existing Domain Name System, that would access the page registered by the owner of the RealNames keyword.
In effect, to users of Internet Explorer, RealNames became a domain registry which was capable of registering names that worked without needing to belong to a top level domain such as ".com" or ".net". RealNames and its backers expected this to be a lucrative source of income, and it raised more than $130m of funding for its venture.
RealNames was dependent on maintaining its association with Microsoft that enabled the RealNames service on Microsoft's web browser. RealNames shut down operations in 2002 following a decision by Microsoft to redirect the 1 billion page views per calendar quarter that RealNames were resolving from the browser address bar into the MSN search engine.
