Google says if it gets enough complaints about something, it will slide those sites lower in search results, make them harder to discover. That something this time is websites that transmit non-copyrighted material -- bootleg music and movies on file-sharing sites. That's because Google needs to score points with the entertainment industry. It wants to sell more music and movies through its Google Play store. It wants cable channels to play along with Google TV and with Google Fiber. And it could all affect your Google searches.
