Privacy in the 21st century?

We are living in a world, where public and private spaces have been blurred by technology.
Technology brought people the new era, where life was promised to be a much better place to live, but it seems like we have exchanged privacy with technology.

From mobile phones to social networking sites, we are constantly monitoring other people and we a monitored by others. We log on to Facebook to catch up with our friends where we can see pictures of our friends and comments made by them, we receive texts and phone calls from our friends and family. Privacy is no longer active in the world where we are living and breathing because we are constantly in surveillance by the people that are around us.
When we go to supermarket for example we might see a coupon saying 20% off a product and all we need were to give up a few of our personal information to get that discount coupon. Marketers have learned how to seduce consumers with discounts and it shows how vulnerable people are in giving out its personal information.

Tools for tracking people which once was used by the government in the past but now in the digital age large corporations have access to these tools. With the constant development in the digital age the word privacy is becoming more and more irrelevant and the world public is becoming more relevant.
