It's official: Google's Street View has now officially reached all seven continents. Google today announced that it has added Brazil, Ireland, and Antarctica to its Street View library, which provides panoramic images of street-level scenes from locations around the world. It's a major milestone for Google's three-and-a-half year old service, but it's not one that will be universally celebrated, as Street View is now (and has been, almost since its launch) under fire for its alleged privacy violations and data collection practices. What Is Street View, Anyway?Privacy concerns aside, Street View is pretty darn cool. By sending an army of drivers in special camera-equipped cars out to cruise the world's roads, Google was able to compile panoramic, 360-degree images of locations around the world. You can switch to Street View from within Google Maps, so you can see exactly what a place looks like without having visited. And the Backlash Begins
