Nielsen started measuring “demographic data” on age and gender for its Twitter TV ratings, said a company news release (http://bit.ly/1o7LotO) Monday. Initial demographic data showed a “broad age and gender distribution across programming” and “highlights significant differences in age and gender profiles across programming types,” it said. The new data illustrate “how Twitter enables TV networks and advertisers to reach audiences beyond their core demos,” it said. The data advances “our ability to evaluate and measure the impact of those opportunities and complement our clients’ TV investments with social activation that can improve overall marketing performance,” said David Shiffman, MediaVest executive vice president-research, in the release.
