Quick Reference

See also audience measurement.

1. An independent measure of the relative popularity of particular television or radio programmes in terms of the number of viewers and the audience share (based on a representative audience sample). In media buying, a rating is the percentage of a particular demographic group constituting the audience for a specific TV or radio programme on average per minute; accumulated ratings are called gross rating points (GRP), used to calculate reach and frequency. Ratings are particularly important for commercial broadcasters, who charge more for advertisement slots during high-rated programmes.

2. Weekly tables of the most popular television programmes in rank order made available for the general public (e.g. in listings magazines).

3. (appreciation index) Audience scores relating to their evaluation of the relative quality of particular radio or television programmes.

4.Rating systems for classifying films according to their suitability for audiences: see certification.
