Brian Rakowski walks to the whiteboard in a small conference room in Building 41 on Google's Mountain View campus. A lanky, gregarious man in his twenties, Rakowski is the product manager of a top-secret project that's been under way for more than two years. The weekly Monday meeting of managers � or "leads," as Google puts it in its nonhierarchical way � will be one of the last before the upcoming launch. Rakowski writes 12 items on the board with a black dry-erase marker. The first is "State of the Release." It's late August, and the release in question is called Chrome, Google's first Web browser. Since a browser is the linchpin of Web activity � the framework for our searching, reading, buying, banking, Facebooking, chatting, video watching, music appreciation, and porn consumption � this is huge for Google, a step that needed to wait until the company had, essentially, come of age. It is an explicit attempt to accelerate the movement of computing off the desktop and into the cloud � where Google holds advantage. And it's an aggressive move destined to put the company even more squarely in the crosshairs of its rival Microsoft, which long ago crushed the most fabled browser of all, Netscape Navigator.
