I was part of the Netscape Navigator engineering team. Lots of great stories regarding the early days of the Internet. One of my favorites was the origin of the hand icon for links:

Even small innovations at the time seem bigger in retrospect. For example, it was Mittelhauser who came up with the hand icon for links: “It was really, really easy to change the icon on Windows. It was a single call. So, I’m like, “Oh, when it goes over a hyperlink it’s sort of Windows standard; you change to the hand icon to indicate you can click on it.” That was five minutes of work. And then of course that forced everybody else to go do it because it was a good idea and it was popular. There was often a competitive aspect of trying to come up with the cool thing; get it done first.”
