The New York Times > Technology > Google Envy Is Fomenting Search Wars: "Future competition for domination of the Internet may also mean refighting the battles of the past - in particular, the Web browser wars. There have been reports that Microsoft's control of the browser market may be loosening. America Online, for example, is thought to be preparing to re-enter the market with a new browser.
Google is also rumored to be developing a Web browser as part of its strategy to defend itself against Microsoft, whose new Web search service will almost certainly be integrated into Internet Explorer.
'If you drive by the Google buildings in the evening,' said a person who has detailed knowledge of the company's business, 'the lights that are still on are the ones on the floor where they are working on the browser.'"
