Whether you liked the ending of "Lost" or not, the just-ended TV show has generated more buzz than any other show in the social media sphere. 

It has averaged more posts and tweets than "American Idol," second among TV shows for online chatter, according to social media monitoring firm Networked Insights.

The firm just introduced a TV tracking tool last week to help networks better understand what fans are saying about them online. It's called SocialSenseTV, and we recently sat down with Networked Insights CEO Dan Neely to discuss how the service works.

In a nutshell, Networked Insights amasses data from 1.5 billion online conversations each month to determine trends. This data is being used by both TV networks and brands to better understand consumers.
