 Netscape Navigator 3 was the undisputed web browser giant in its time with over 90% share, but it was later eroded by the free Internet Explorer included with Windows 95.Netscape 4 addressed the problem of Netscape Navigator being used as both the name of the suite and the browser contained within it by renaming the suite to Netscape Communicator.After releasing five preview releases from 1996–1997, Netscape Corp. released the final version of Netscape Communicator in June 1997.
