We hear the term big data all the time. Everything we buy, click on, and publish online becomes part of big data. It is everything about us and the world we live in. This includes our buying habits, our routines, and our thoughts and jots. Companies can use big data to determine buying trends to determine what people will buy and when. It tells us all kinds of information, but takes a lot of processing power to make something useful of the data. But, is it really necessary? Or is better to not know so much? What else can the data be used for. Is it an invasion of privacy? This documentary will touch on some of these topics.
