A new superpower just entered the long-simmering browser war: On Tuesday, after years of secret work, Google, the world's most popular search engine, will unveil its own browser, called Chrome.
The software, which is in beta, will be distributed for free to PC users in over 100 countries via Google's blog. (Mac and Linux versions are in the works.) Word of the impending launch accidentally leaked Monday when Google mistakenly sent a comic-book-style announcement, detailing Chrome, to a blog.
