When someone says "Big Brother", everybody's first instinct is to think of the government. Really though, who is big brother anymore?
To me, big brother is the myriad of corporations, individuals and groups (up to and including) the government that are constantly bombarding me with advertisements and generally trying to influence me away from my money and/or sanity.
They want to know us, and they want to know everything about us. Now, they've finally got the means to know all about us and the things we like. Of course they always attempted to, but now they don't even have to work for it. Just look at the charts that Lusche provides, and the amount of information that can be disseminated from them. Well, the corporations, individuals and groups have the same types of graphs going on, and are drawing a wealth of information about us from them. All based upon the various activities that we engage in on the internet (especially Facebook).
Well I say, "Screw you Ad-man. If you want to find out anything about me, you'll have to come find me."
