Final answer:
A limitation associated with the use of radio as an advertising medium is audience fragmentation due to the high number of stations in most markets. Radio advertising may also be more expensive than TV advertising.
Step-by-step explanation:
A limitation associated with the use of radio as an advertising medium is the high number of stations in most markets, which leads to a great deal of audience fragmentation. With so many stations to choose from, advertisers may struggle to reach their target audience effectively. For example, if a company wants to target a specific demographic, such as young adults, it may need to advertise on multiple stations to reach that audience.
It is important for advertisers to carefully consider their target market and select radio stations that align with their audience demographics and interests. Additionally, radio advertising may be more expensive than buying advertising space on television because of the demand and competition for airtime.
