Audience measurement
Audience measurement measures how many people are in an audience, usually in relation to radio
listenership and television
viewership, but also in relation to newspaper and magazine
readership and, increasingly, web traffic on websites. Sometimes, the term is used as pertaining to practices which help broadcasters and advertisers determine
who is listening rather than just
how many people are listening. In some parts of the world, the resulting relative numbers are referred to as
audience share, while in other places the broader term market share is used. This broader meaning is also called
audience research. Measurements are broken down by media market, which for the most part corresponds to metropolitan areas, both large and small.
