For years, TV networks have asserted that Nielsen ratings are an inaccurate way to determine a show's popularity. Their case hold more water now that a significant percent of audiences time-shift their viewing (via DVR or online streaming services like iTunes or Hulu). As a side-effect of that, many networks have combated dwindling ratings by trumpeting their social metrics and declaring themselves The Most Social Show of a given night.
But what does being "a social show" really mean and how is that data collected?
One way is through a service like Trendrr.tv -- a 6-year-old company that pulls from Twitter, Facebook, Get Glue and Viggle to deduce which shows are generating the most online conversation.
