For those of you who are unaware of these finer details, 0.9 was the first release of the Netscape browser (which begat Firefox) available to the general public. This beta release was an unannounced surprise. Prior to this, everyone assumed that what we were doing was going to be a standard for-sale product where you sent off your $35 and then some time later got a disc in the mail with a license key. That we just said, “Here’s our FTP site, come get it, go crazy” was, at the time, shocking to people.

The thing that confuses people sometimes about new platforms is that while the platform and its clients are different things, you usually need both to be great for the whole thing to succeed. The World Wide Web, as conceived by Tim Berners-Lee, was and remains a remarkable, world-changing platform. But it really didn’t take off until Netscape hit. It was just such a great app, including on the Mac. It was the browser the web needed.
