The Nielsen television ratings collation group Nielsen has published a report confirming a statistically significant” link between Twitter activity and programme ratings. The findings suggest a virtuous cycle, with a boost in one directly affecting the other. The report states that tweets both drive consumers to tune-in to a program, and increase chat about shows they are already watching. It claims “statistical evidence of a two-way causal influence between broadcast TV tune-in for a program and the Twitter conversation around that program.”
