Today Google Finance is celebrating its fifth birthday. It started of on March 21, 2006 with pricing data from the NASDAQ, New York Stock Exchange, Amex and Euronext. Their most innovative feature at that time was the interactive chart, which we are quite familiar with now a days, that seamlessly scrolled, zoomed, and showed a timeline of news coverage for each company. Later that year they added the ability to track investments in a portfolio.
In 2007 Google launched their first mobile application and iGoogle gadget. To add to it, they added the GoogleFinance functions which allow easily incorporation of financial information into a Google Spreadsheets.
