Final answer:
some statements about Radio and the CDJ are inaccurate, highlighting the limitations of radio compared to digital platforms for audience outreach and CPM assumptions. Radio's effectiveness varies by audience and context, with community radio providing a unique local reach.
Step-by-step explanation:
Among the statements about Radio & the CDJ, certain assertions are false:
- Statement a, which suggests that most reach is driven through nationally syndicated radio programs and hence building reach is inexpensive, is false because radio is not as effective in reaching voters or the audience compared to social media and the Internet, which are cheaper and more successful.
- Statement d, which talks about CPMs being relatively low and allowing for greater numbers of spots, does not accurately reflect the competitive and sometimes high costs of advertising on popular radio shows or syndications. While it's true that low CPMs exist, they are not uniformly low across all radio platforms.
On the contrary, satellite radio is expanding rapidly and has relative success with its subscription model, thanks to companies like SiriusXM. Community radio, with its focus on local content and public participation, provides a contrasting approach to commercial radio, often having low wattage and working on a nonprofit basis.
Overall, the landscape of radio as a medium for reaching audiences is complex and varies depending on factors such as the target demographic, the nature of the message, and the geographic and cultural context.
