MADISON Ave. can now measure how addicted you are to your favorite shows.
Turns out that "Survivor," the long-running reality show heading into its 17th edition, has the highest loyalty rating, according to a new measure called the Emotional Attachment Index (EAI).
While Nielsen ratings measure the raw numbers of people who are watching a show at any given time, the EAI - created by the same Long Island research company that supplies the famous "Q scores" of TV personalities - indicates the passion viewers have for the shows they watch.
It is done, in part, by determining a viewer's commitment to watch a particular show in the future.
Among the other high-scoring EAI shows are "Heroes," "House," "Grey's Anatomy" and the little-watched-but-apparently-well-loved CW series "Supernatural."
