Final answer:
The question revolves around the capabilities and characteristics of Arbitron's RADAR, a service for measuring radio audience sizes and preferences. RADAR is likely focused on providing data on radio audiences, contrasting with activities like television audience measurement or diary interviews.
Step-by-step explanation:
The question pertains to Arbitron's RADAR, a service known for measuring radio audiences. Options A through E present different statements about RADAR to assess its functions and characteristics. It's important to note what RADAR does and how it fits into the context of media advertising and audience measurement.
Within the context provided, television and radio operate differently as media platforms. Television advertising benefits from sophisticated data on viewer demographics, allowing for targeted advertising. Radio, although considered less effective for broadcasting compared to other media forms, still captures specific audience segments, especially in local markets. Moreover, recent developments in media, such as satellite radio companies like SiriusXM, introduce subscription models that contrast with conventional radio's reliance on advertising for revenue.
Given this information, we can determine that the correct statement regarding Arbitron's RADAR is not explicitly provided in the options. However, by inference, we understand that RADAR focuses on radio audience measurement, suggesting it would not primarily measure TV viewership for local stations (C), and it would more likely collect data over time rather than from just diary interviews (D).
