Final answer:
A limitation associated with radio as an advertising medium is audience fragmentation due to the high number of stations. Radio also lacks opportunities for integrated marketing. These limitations should be considered in marketing campaigns.
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. This means that advertisers may have a harder time reaching their target audience due to the wide variety of options available.
Another limitation is that radio is unable to provide marketers with a variety of integrated marketing opportunities. Unlike some other mediums, radio does not offer as many options for combining advertising with other promotional activities.
Overall, while radio can be a valuable advertising medium, these limitations should be considered when developing a marketing campaign.
