I can't remember the name of the company that MS bought the rights to the
browser that MS renamed IE then gave it away free so they didn't have to
live up to their contractual royalty payments. It took awhile but MS lost
that one also.
Spyglass. Netscape's Mozilla browser was based on Spyglass libraries.
Microsoft also based IE on Spyglass, and agreed to pay royalties on each
copy of IE sold. Then they bundeled IE into Windows, raised the price of
the bundle, and said they were giving IE away for free so they didn't have
to pay Spyglass anything. Spyglass sued and eventually won a relatively
small amount of damages. By then the company was dead because, with IE
being bundled "for free" with Windows, there was no market for commercial
browsers and thus no reason for commercial developers to pay to license
Spyglass' libraries.
For those who don't know the rest of the story, Microsoft's bundling of IE
also killed Netscape's sales, and Microsoft further rigged Windows and
their OEM licenses so as to keep a constant pressure on users to give up
on using Netscape:
"We're going to cut of their air supply." -- Microsoft Senior Executive
Paul Maritz
"It will be very hard to increase browser share on the merits of IE4
alone. It will be more important to leverage the OS asset to make
people use IE instead of Navigator." --Microsoft Senior Executive
Christian Wildfeuer
For those who don't know the history of Firefox: When they died, Netscape
retaliated by open-sourcing Mozilla's code. Firefox was, originally, just
the web-browser part of Mozilla (iow, Mozilla minus the newreader and
email clients) but its taken on a life of its own. Being open source,
Firefox benefits from the OSS distributed-development model which allows
programmers from all over the world to pool their talents - meaning that
there are more programmers contributing to Firefox than even Microsoft can
muster. Not only is Microsoft finding it very difficult to keep up, but
they can't buy Firefox nor - since Firefox is free - is there any "air
supply" for them to cut off.
I bet Mark Andreeson (co-founder of Netscape) is laughing his head off.
