There were an estimated 30 million surveillance cameras in the
United States in 2011. Video surveillance has been common in the United States since the 1990s; for example, one manufacturer reported net earnings of $120 million in 1995. With lower cost and easier installation, sales of home security cameras increased in the early 21st century. Following the September 11 attacks, the use of video surveillance in public places became more common to deter future terrorist attacks. Under the Homeland Security Grant Program, government grants are available for cities to install surveillance camera networks. In 2009, there were an estimated 15,000 CCTV systems in Chicago, many linked to an integrated camera network. New York City's Domain Awareness System has 6,000 video surveillance cameras linked together, there are over 4,000 cameras on the subway system although nearly half of them do not work, and two thirds of large apartment and commercial buildings use video surveillance cameras. In the Washington D. C. area, there are more than 30,000 surveillance cameras in schools, and the Metro has nearly 6,000 cameras in use across the system. The Cheshire
figure is regarded as more dependable than a previous study by Michael McCahill and Clive Norris of UrbanEye published in 2002.

While much of what Orwell seemed to fear has become a reality in today’s world, the current reality of the negative consequences of participatory surveillance far surpasses what Orwell envisioned. Participatory surveillance is engaged in when individuals knowingly allow websites to access personal information entered in profiles and online forms as well as when easily gathered recordings of oneself and others through commonly owned mobile technology. This process is a type of passive permission for others such as insurance companies, marketing firms and service providers to gain access to our online information even when we have some semblance of a reason to believe it will be kept anonymous or private. The novel 1984 was authored by a liberal and objective socialist not long after the Second World War had ended. The book discusses a future in a
totalitarian state where people’s thoughts and behaviors are minutely monitored, interpreted as indicating party alliance or party misalliance and controlled to increase or decrease them depending on the valence. The entire novel was based on a “what if” questions, specifically what if Bitiain had lost the war. Orwell found himself wondering what Britain might have looked like if it fell under the rule of either one of the totalitarian powers that dominated the mid 20th century. From that basic question, 1984 was created. Orwell presents a dark, unfulfilling, over politicized society, which is deemed tolerable for the safety it provides. From the beginning however, Orwell presents the protagonist as having a passionate individual side that calls to revolt, despite being somewhat pitiful in the opening scenes. While the ear 1984 has come and gone long ago, the disturbing yet strangely prophetic vision George Orwell presented in 1949 continues to be timelier with each passing decade.
