This is an in-depth study of users and usage—averaged across the U.S. population—with the purpose of aligning methodologies and metrics to display an “apples to apples” view of consumption across TV, radio, TV-connected devices, PCs, smartphones and tablets.
The core purpose of this report is to address three basic concepts equally applicable to all categories of media measurement: how many, how often, and how long.
All of the findings were derived from the best available data in the reporting periods of March 27-June 25, 2017 and March 28-June 26, 2016.
