Do you have cable TV?  They already do some of this, and plan to do
more; all supposedly "anonymized", but there are plans to deliver
"targetted" ad streams to households, based on neighborhood
demographics.  Tivo already "recommends" stuff to you, so they are
even able to derive your interests (somewhat - google "My Tivo think's
I'm gay!")
