Well, they can't get a patent on it now... the idea is in the public domain now!
How about a genetically engineered virus that goes into the infected person's brain and attaches to the cochlear nerve and constantly plays commercials. The company that engineers the virus sells ad space to the highest bidder.
Capitalism at it's best!
