Arbitron has developed special procedures for emergency conditions to help manage sample delivery. They claim to closely monitor market conditions, including listening to survey respondents and PPM panelists, and implement contingency plans when necessary.
If a natural disaster or crisis occurs, stations are encouraged to report any technical difficulties that last for five or more consecutive minutes.
Tom’s Take: There are those who don’t like to report down time. If a diary contains a reference to your station, but you have reported if off-air to Arbitron, you lose the credit.
