There was a time, dear ones, when a giant walked the Web: Netscape Navigator, the browser sovereign, held a massive 80%+ share of the market back in the mid-1990s, until some funny business (where "funny" = "anticompetitive & monopolistic") led to the dominance of Microsoft's Internet Explorer browser. The open-sourced core of Netscape 4 led to the development of the Mozilla, Firefox and Camino browsers we all love today.
Whence the original Netscape browser? The 8.0 release skipped the Mac, but believe it or not, the big N is back: Netscape Navigator 9 beta is available now as a Universal Binary. Under the surface, Navigator 9 is really a rebranded, tweaked and gracefully skinned version of Firefox 2.0 (including add-in compatibility), but nevertheless it's nice to see the green giant back in the saddle.
Note: TUAW and the Weblogs, Inc. network are corporate siblings of Netscape under the AOL umbrella.
