Meters for measuring radio audiences

摘要

Knowing just how many people are listening to a radio programme is vital for broadcasters. D J A Walker discusses the latest technology for audience monitoring. It is important to broadcasters to have a measure of the size of the audience listening to, or watching their programmes. Feedback of audience size is significant in determining scheduling, continuance of series, and many other broadcast management decisions. To a commercial station, audience size has a direct relationship to fees charged for advertisements. Public service broadcasters need to demonstrate that licence payers watch their programmes to justify their funding.
