MarketingMagic

1. Why would anyone who lives in a city where the drinking water is clean, good-tasting, and free of charge pay $1.50 for a glass of bottled water? Odd though it may seem, this is a daily occurrence in New York City and has been since 1977, when Perrier water was first introduced in the United States. Perrier, a lightly carbonated water from the south of France, is chic. It became that way because the company that bottles Perrier had a very smart marketing strategy.

2. A marketing strategy is a plan for presenting a product so that it will be as attractive as possible to potential buyers, regardless of any intrinsic merits the product may have. Before Perrier came to the United States, Americans rarely drank bottled water, and then only when they feared the local water supply was contaminated. But the Perrier people changed that by appealing to Americans who were highly conscious of three things: health, weight, and fashion. Perrier was presented as a sparkling, natural drink, free of alcohol and other dangerous chemicals. But not only was it good for you, it was French. Therefore it was sophisticated as only a French drinking water could be. With this strategy, Perrier sold over 40 million bottles of water in the United States in one year.

3. Another example of marketing magic is "designer jeans." For over a hundred years, miners, farmers, and cowboys have worn jeans because they were made of sturdy blue denim that didn't wear out. They were simply the best work pants in the world.

4. But a Hong Kong businessman, Mohan Murjani, wasn't interested in selling something practical and durable. For him, jeans were a marketing problem and he wanted a new way of presenting them to the public. He decided to make a new kind of jeans, not for working cowboys, but for people who wanted to look glamorous. And Murjani succeeded. By 1978, 17% of all jeans sold were tight-fitting designer jeans. They cost no more to make than cowboy jeans, but they sold for four or five times as much. Why? Because people will pay more for fashion than they will for work clothes. And if the marketing strategy is right, anything can be made fashionable. (World English)
