Boasting a $112 billion market capitalization that now almost doubles Yahoo, Google stock on Thursday surged past the $400 a share for the first time. In the past four weeks, Google shares have shot up over $100, with talk that $500 could be within reach before long.

Google rolled out Google Base Wednesday, which allows users to upload any type of content to the search engine's Web site to be categorized and searched. On Thursday, the company said it was opening offices in Sao Paulo, Brazil and Mexico City in an effort to extend its Latin American reach. Google previously had a research center in Brazil through its acquisition of Akwan in July.
