Final answer:
Paid advertising has the potential advantage of yielding a large number of controlled impressions.
Step-by-step explanation:
The statement is true. While publicity is desirable because it is relatively low-cost, paid advertising has the advantage of yielding a large number of controlled impressions. Candidates running for political office often invest a significant portion of their campaign resources into TV ads, as they can reach a wide audience and create a controlled message. Additionally, paid advertising allows candidates to target specific demographics and geographic areas for maximum impact.
