It took a few years longer than anticipated, but Netscape Navigator is finally being discontinued as of February 2008:
While internal groups within AOL have invested a great deal of time and
energy in attempting to revive Netscape Navigator, these efforts have
not been successful in gaining market share from Microsoft's Internet
Explorer. Recently, support for the Netscape browser has been limited
to a handful of engineers tasked with creating a skinned version of
Firefox with a few extensions.
AOL's focus on transitioning to
an ad-supported web business leaves little room for the size of
investment needed to get the Netscape browser to a point many of its
fans expect it to be. Given AOL's current business focus and the
success the Mozilla Foundation has had in developing
critically-acclaimed products, we feel it's the right time to end
development of Netscape branded browsers, hand the reigns fully to
Mozilla and encourage Netscape users to adopt Firefox.
While we will no longer support the Netscape web browser as of February 1, 2008, Netscape.com will still continue to serve as a general use Internet portal.
As I noted when Navigator 9 was released recently, this project has been a complete waste of time in recent years. This was long overdue.
