Ingeniously, Chrome itself need not take a lot of market share to fulfil Google’s objectives. Google does not expect to sell or otherwise “monetise” Chrome directly. Like Firefox’s, Chrome’s source code is free for anybody to change and improve, and even for rival browser-makers to incorporate. That could even include Microsoft. As Mr Brin says, “we would consider it a success” if the next version of IE were “built on Chrome, or even if it were just a lot better as a result of Chrome.” Google wants ever more people doing ever more things on the web, and peace of mind that nobody, not even Microsoft, can interrupt that.
