NCSA was before them, and Netscape (and later Mozilla after server business didnt materialize) basically clean-room copied NCSA from scratch.  Pioneers in new directions can define space but still get slaughtered because the next entrant (Chrome) doesn&#x27;t have product inertia and has&#x2F;should learned lessons of what didn&#x27;t work.<p>Some of it maybe popularity&#x2F;marketing of not having a huge org behind them, but odd rough-edges did more to sabotage stickiness.  Plus, competing with deep pockets giving away something for free is an unnecessary competitive war of attrition, especially by not differentiating: most secure browser or best browser for X&#x2F;Y&#x2F;Z.
