In observance of the 10th anniversary of Mosaic Eric Sink has written a very interesting piece from an insider's perspective of the browser wars and how Spyglass Mosaic eventually became Internet Explorer.

Talking about the turning point in the browser war:

For the development of IE 4.0, a new Program Manager appeared.  His name was Scott Isaacs and I started seeing him at the HTML standards group meetings.  At one of those meetings we sat down for a talk which was a major turning point for me and for Spyglass.  Scott told me that the IE team had over 1,000 people.

I was stunned.  That was 50 times the size of the Spyglass browser team.  It was almost as many people as Netscape had in their whole company.  I could have written the rest of the history of web browsers on that day -- no other outcomes were possible.

Eric Sink later left Spyglass and went on to found SourceGear, creators of the popular SourceOffsite product and one of my favorite companies to watch grow.
