Guest Viewing
In television audience measurement, peoplemeter operations approximate panel members' total domestic viewing, whether in home or in someone else's home by measuring the viewing of guests in panel members' homes. This viewing can be regarded as a substitute for the panel members' own viewing when they are guests in unmeasured homes. Guest viewing is measured by asking visitors in a panel home to register their presence by using a special guest button on the hand set. They are also asked to give basic demographics (sex and age).
