Remember Netscape? Founded in 1994, it owned 90 percent of the global browser market after only a couple of years. Overnight that market share dropped to one percent when Netscape was taken out by Microsoft's Internet Explorer.

When you hear Arthur Goldstuck tell the story, you realise it wasn't the competition that killed Netscape. It was arrogance. At the time, Netscape didn't believe anyone else could create a better browser.
