I noticed that one, too. But I think "winning" would really be if MS bought you and incorporated you into the OS (which it has done with an awful lot of stuff).
BTW: there was also one before, that PKZip was based on (actually infringing on its copyright, and ended up being very upsetting to the originator).
Wasn't over once before, and PKZip won? And later it was over again, and WinZIP won?
