UHF Viewing and Television Channel Selector Type

摘要

The report is a statistical analysis of the relationship between UHF viewing and television channel selector type. It is based on a data set that contains information on UHF, VHF and total viewing on over 3,800 individual television receivers, information on the channel selector on each set, and information on receiver, antenna and household demographic characteristics. The data, which were collected under contract by the Arbitron Company, were assembled from diaries and follow-up telephone interviews. An exhaustive examination of this data set revealed no evidence of a systematic relationship between UHF viewing and channel selector type. In particular, no evidence was found that electronic channel selectors are associated with higher levels of UHF viewing. The report concludes that assertions that channel selectors have a substantial effect on UHF viewing should not be accepted in the absence of empirical evidence demonstrating the existence of a relationship.
