The Role of Trust in Audience Measurement
Audience measurement is an inexact science to say the least. That’s not to say that it is seldom “right” or that media managers can’t or shouldn’t make important decisions based on research reports. But in order for audience research to be respected, consumers of research must be able to trust the integrity of the data used to make important decisions…decisions that almost certainly have huge financial implications. Take television ratings for example. Ratings are used to set advertising rate cards and programming schedules. Each year about $60 billion of TV advertising is “allocated” based on Nielsen’s data. Meanwhile, careers of actors, writers, producers, and programmers live or die based on the “numbers” that Nielsen sells to media corporations. And for the most part, Nielsen is the only game in town. Others have tried to break into the TV ratings business, but with little success.
Not only do media companies need to have confidence in Nielsen’s data, they need to have confidence in Nielsen the company. And in recent years that has been a point of contention. It’s easy to criticize Nielsen on a variety of fronts. From sample size, to data collection methodology, to weighting and reporting, Nielsen’s measurement of the nearly 107 million US TV households (TVHHs) has been criticized, and not just by the networks who appear at the bottom of the ratings pile. One group (Don't Count Us Out) is even suggesting that there may be a conspiracy by Nielsen to under count African American and Hispanic viewers.

The roll out of the A/P (active/passive) meter on April 7th is just the latest attempt by Nielsen to restore confidence in their data. The A/P meters are designed to measure TV viewing taking place via digital platforms such as digital set-tops and digital video recorders, and to measure in a variety of locations…not just the home. Time will tell if the A/P meter is the solution to Nielsen’s credibility gap.
