Internet search giant Google’s ‘Street View’ service has successfully encompassed all the seven continents of the world in just three-and-a-half years since its launch in 2007.

Google Street View is now available in Antarctica, the continent inhabited mostly by penguins. The state-of-the-art technology provides users with panoramic, 360-degree images of the streets. But, interestingly, there are no streets in Antarctica.

For the moment, the Street View images of Antarctica are restricted to user-contributed shots of penguins on Half Moon Island plus panoramic landscapes.

In addition to Antarctica, Google Street View was also launched in Ireland and Brazil, taking the total to twenty-five.

Privacy advocates have been opposing Google Street View service since it was first launched in America in 2007, saying it could jeopardize the security of the users and their property.

Conversely, Google claimed that the service would be very useful to all, even to the penguins. The company also claims that it attracts more tourists by providing them with an opportunity to explore popular tourist attractions.

The service has also been lambasted by some of governments. The Czech Republic authorities earlier this month put a ban on Google Street View, claiming the service incongruously meddle with people's privacy.
