DIFFUSION OF ADVERTISING MESSAGE

 

DIFFUSION OF INNOVATION:          The diffusion of innovation refers to the tendency of new products, practices, or ideas to spread among people. Usually, when new products or ideas come about, they are only adopted by a small group of people initially; later, many innovations spread to other people. The bell shaped curve frequently illustrates the rate of adoption of a new product. Cumulative adoptions are reflected by the S-shaped curve. The saturation point is the maximum proportion of consumers likely to adopt a product. In the case of refrigerators in the U.S., the saturation level is nearly one hundred percent of households; it well below that for video games that, even when spread out to a large part of the population, will be of interest to far from everyone. Several specific product categories have case histories that illustrate important issues in adoption. ATM cards spread relatively quickly. Since the cards were used in public, others who did not yet hold the cards could see how convenient they were. Although some people were concerned about security, the convenience factors seemed to be a decisive factor in the “tug-of-war” for and against adoption. Rap music initially spread quickly among urban youths in large part because of the low costs of recording. Later, rap music became popular among a very different segment, suburban youths, because of its apparently authentic depiction of an exotic urban lifestyle.

 

DIFFUSION OF ADVERTISING MESSAGE:            The diffusion process of advertising message refers to the acceptance of new products and services by the members of a community or a social system. For a marketer, it would be obviously beneficial to have an understanding of a process by which people learn about new products, try them and eventually accept or reject them. The diffusion theory, a body of knowledge that has been evolved from sociology, provides this kind of understanding. Central concept of the theory is that there is a process of diffusion by which an innovation about product or service spreads from its source of invention or creation to its ultimate users or adopters.

 

ELEMENTS:     Four elements are required for diffusion process of an advertising message:

ü    An innovation, which is an idea or a product or a service that is perceived new.

ü    Its communication from one individual to another

ü    Its penetration from one individual to another

ü    Its use over a period of time

 

CHARACTERISTICS OF AN INNOVATION:          The characteristics of an innovation vary from one product to another, and tend to vary between geographic area and culture. These characteristics are summarized as: Relative Advantage: This refers to the superiority of the innovation over existing offers. Compatibility: Innovation has compatibility if it fits with the values and life-style of the prospects. Complexity: It means the degree of difficulty that consumers experience in understanding how it works and in using it. Divisibility: It is the extent to which the innovation may be used on a limited basis.

Several forces often work against innovation. One is risk, which can be either social or financial. For example, early buyers of the CD player risked that few CDs would be recorded before the CD player went the way of the 8 track player. Another risk is being perceived by others as being weird for trying a “fringe” product or idea. For example, Barbara Mandrell sings the song “I Was Country When Country Wasn’t Cool.” Other sources of resistance include the initial effort needed to learn to use new products (e.g., it takes time to learn to meditate or to learn how to use a computer) and concerns about compatibility with the existing culture or technology. For example, birth control is incompatible with strong religious influences in countries heavily influenced by Islam or Catholicism, and a computer database is incompatible with a large, established card file. Innovations come in different degrees. A continuous innovation includes slight improvements over time. Very little usually changes from year to year in automobiles and even automobiles of the 1990s are driven much the same way that automobiles of the 1950 were driven. A dynamically continuous innovation involves some change in technology, although the product is used much the same way that its predecessors were used—e.g., jet vs. propeller aircraft. A discontinuous innovation involves a product that fundamentally changes the way that things are done—e.g., the fax and photocopiers. In general, discontinuous innovations are more difficult to market since greater changes are required in the way things are done, but the rewards are also often significant. Several factors influence the speed with which an innovation spreads. One issue is relative advantage (i.e., the ratio of risk or cost to benefits). Some products, such as cellular phones, fax machines, and ATM cards, have a strong relative advantage. Other products, such as automobile satellite navigation systems, entail some advantages, but the cost ratio is high. Lower priced products often spread more quickly, and the extent to which the product is trialable (farmers did not have to plant all their land with hybrid corn at once, while one usually has to buy a cellular phone to try it out) influence the speed of diffusion. Finally, the extent of switching difficulties influences speed—many offices were slow to adopt computers because users had to learn how to use them. Some cultures tend to adopt new products more quickly than others, based on several factors:

·                    Modernity: The extent to which the culture is receptive to new things. In some countries, such as Britain and Saudi Arabia, tradition is greatly valued—thus, new products often don’t fare too well. The United States, in contrast, tends to value progress.

·                    Homophily: The more similar to each other that members of a culture are, the more likely an innovation is to spread—people are more likely to imitate similar than different models. The two most rapidly adopting countries in the World are the U.S. and Japan. While the U.S. interestingly scores very low, Japan scores high.

·                    Physical distance: The greater the distance between people, the less likely innovation is to spread.

·                    Opinion leadership: The more opinion leaders are valued and respected, the more likely an innovation is to spread. The style of opinion leaders moderates this influence, however. In less innovative countries, opinion leaders tend to be more conservative, i.e., to reflect the local norms of resistance.
