But these days, if you look at a U.S. map on Google, the only copyright notice you are likely to see is Google’s. In the course of driving the country collection pictures for Google Street View, Google has built up its own database of maps as well as the data needed for turn-by-turn driving instructions.

Google’s possession of its own map data and its willingness to make it available free, though sometimes sprinkled with ads, could be very bad news for companies that have spent a fortune building and maintaining map information databases. Suddenly, two of last year’s big deals, Nokia’s $8.1 billion acquisition of Navteq and TomTom’s $4.3 billion purchase of Tele Atlas, look like they may not have been among the swiftest of corporate M&A moves.
