I was chatting the other day with a colleague about the state of the "browser wars," and he sent me this documentary, made in 2000, on the creation of Mozilla out of Netscape. I just watched it and it's really good.
Netscape doesn't exist anymore, but the crazy vision of giving away the source code for free ultimately won. Internet Explorer still has the market share of most default Windows users, but Firefox is a huge player, along with Safari, Chrome, Opera, and others. Microsoft was forced to cooperate with web standards; open source software has grown exponentially; and the internet owes a great debt to Netscape's work.
