Twitter activity drives TV viewing, and vice versa

"Today Nielsen released findings, which, for the first time, provide statistical evidence of a two-way causal influence between broadcast TV tune-in for a program and the Twitter conversation around that program. Nielsen’s Twitter Causation Study included time series analysis to determine if Twitter activity drives increased tune-in rates for broadcast TV and if broadcast TV tune-in leads to increased Twitter activity. This latest study follows research released earlier this year that quantified the correlation between TV ratings and Twitter.
Analyzing minute-to-minute trends in Nielsen’s Live TV Ratings and Tweets for 221 broadcast primetime program episodes using Nielsen’s SocialGuide, the findings show that Live TV ratings had a statistically significant impact in related Tweets among 48 percent of the episodes sampled, and that the volume of Tweets caused statistically significant changes in Live TV Ratings among 29 percent of the episodes. The time series analysis methodology used for this study was developed by Nobel Prize-winning economist Clive Granger, and is widely used in the fields of econometrics, physics, and neuroscience, among others.
“Using time series analysis, we saw a statistically significant causal influence indicating that a spike in TV ratings can increase the volume of Tweets, and, conversely, a spike in Tweets can increase tune-in,” said Paul Donato, Chief Research Officer, Nielsen. “This rigorous, research-based approach provides our clients and the media industry as a whole with a better understanding of the interplay between Twitter and broadcast TV viewing.”"
