A 2012 internal Nielsen study on the 2011 TV season suggested that the alignment of Twitter with TV ratings grew throughout the season, culminating in the strongest relationship during the show's finale. Additional research from Nielsen and SocialGuide will be conducted at the end of the 2012-2013 TV season to compare this study's findings on premiere and midseason episodes to finale episodes of the same programs."The TV industry is dynamic and it was important for us to analyze multiple variables to truly understand Twitter's impact on TV ratings," said Mike Hess, Executive Vice President of Media Analytics for Nielsen. "While our study doesn't prove causality, the correlation we uncovered is significant and we will continue our research to deepen the industry's understanding of this relationship." This research follows Nielsen's recent announcement to create the "Nielsen Twitter TV Rating" for the U.S. market. The Nielsen Twitter TV Ratings are the first-ever syndicated-standard metric around the reach of the TV conversation on Twitter. The ratings are slated for commercial availability at the start of the Fall 2013 TV season. ABOUT NIELSEN Nielsen Holdings N.V.
