Columnist David Carr talks about what that means, and suggests watching British-made Netflix series "Black Mirror" for a glimpse at the creepy factor. It "asks fundamental questions about where this is all headed, not by creating an improbable dystopian future, but by hitting us right where we live. Its world is just one click away from the one in front of us."

A 30-second spot in the Super Bowl this year runs $4.5 million. And a lot of unknown, or little known companies are shelling out for ads.
