CHROME

Microsoft's (MSFT) Internet Explorer has dominated the browser world for nearly a decade.
Recently the Firefox browser, a free product built and supported by the Mozilla Foundation has picked up, by some measures, a 20% . Google (GOOG) will enter the market and do what it can to crush Firefox and take what it can from Microsoft. The product, called Google Chrome, "is designed to make it easier and faster to browse the Web, by offering enhanced address-bar features and other elements that are very different from those on other browsers."
Since Internet Explorer comes loaded on the great majority of PCs, the Google product may not find it so easy to dislodge. Firefox, on the other hand, is in most cases downloaded from the Mozilla website. For Google Chrome to be successful, it would have to take another 15% to 20% of Microsoft's browser share, or take a much larger piece of the Firefox business.
Google's challenge will be to compete for the market of users who are willing to independently locate and download an Internet Explorer option.
