Every day in Britain millions of searches are carried out on Google for free. Every month we spend millions of hours on Facebook for free and read millions of articles from free newspapers.
But now look at it the other way round.
Millions of searches are carried out on sites like Google
Every day Google gathers millions of search terms that help them refine their search system and give them a direct marketing bonanza that they keep for months.
Every week Facebook receives millions of highly personal status updates that are kept forever and are forming the basis of direct advertising revenue.
Every month free newspapers plant and track a cookie tracking device on your computer that tells them what your range of interests are and allows them to shape their adverts and in the future, even content around you.
So you're not just being watched, you're being traded. The currency has changed.
The currency is now information - your information. Businesses can use that information to make big money.
