Helen Troy, owner of three Sound Haus stereo equipment stores, is deciding what message channel (advertising medium) to use to promote her newest store. Her current promotion blend includes direct-mail ads that are effective for reaching her current customers. She also has knowledgeable salespeople who work well with consumers once they’re in the store. However, a key objective in opening a new store is to attract new customers. Her best prospects are professionals in the 25–44 age range with incomes over $38,000 a year. But only some of the people in this group are audiophiles who want the top-of-the-line brands she carries. Troy has decided to use local advertising to reach new customers. Troy narrowed her choice to two advertising media: an FM radio station and a biweekly magazine that focuses on entertainment in her city. Many of the magazine’s readers are out-of-town visitors interested in concerts, plays, and restaurants. They usually buy stereo equipment at home. But the magazine’s audience research shows that many local professionals do subscribe to the magazine. Troy doesn’t think that the objective can be achieved with a single ad. However, she believes that ads in six issues will generate good local awareness with her target market. In addition, the magazine’s color format will let her present the prestige image she wants to convey in an ad. She thinks that will help convert aware prospects to buyers. Specialists at a local advertising agency will prepare a high-impact ad for $2,000, and then Troy will pay for the magazine space. The FM radio station targets an audience similar to Troy’s own target market. She knows repeated ads will be needed to be sure that most of her target audience is exposed to her ads. Troy thinks it will take daily ads for several months to create adequate awareness among her target market. The FM station will provide an announcer and prepare a tape of Troy’s ad for a one-time fee of $200. All she has to do is tell the station what the message content for the ad should say. Both the radio station and the magazine gave Troy reports summarizing recent audience research. She decides that comparing the two media in a spreadsheet will help her make a better decision. a. Based on the data displayed on the initial spreadsheet, which message channel (advertising medium) would you recommend to Troy? Why? b. The agency that offered to prepare Troy’s magazine ad will prepare a fully produced radio ad— including a musical jingle—for $2,500. The agency claims that its musical ad will have much more i m pact than the ad the radio station will create. The agency says its ad should produce the same results as the station ad with 20 percent fewer insertions. If the agency claim is correct, would it be wise for Troy to pay the agency to produce the ad? c. The agency will not guarantee that its custom produced radio ad will reach Troy’s objective— making 80 percent of the prospects aware of the new store. Troy wants to see how lower levels of awareness—between 50 percent and 70 percent— would affect the advertising cost per buyer and the cost per aware prospect. Use the analysis feature to vary the percent of prospects who become aware. Prepare a table showing the effect on the two kinds of costs. What are the implications of your analysis?
