We can see how the product life cycle works by looking at the introduction of instant coffee. When it was introduced, most people did not like it as much as "regular" coffee and it took several years to gain general acceptance (introduction stage). At one point, though, instant coffee grew rapidly in popularity and many brands were introduced (stage of rapid growth). After a while people became attached to one brand and sales leveled off (stage of maturity). Sales went into a slight decline when freeze-dried coffees were introduced (stage of decline).
　　The importance of the product life cycle to marketers is this: different stages in the product life cycle call for different strategies. The goal is to extend product life so that sales and profits do not decline. One strategy is called market modification. It means that marketing managers look for new users and market sections. Do you know, for example, that the backpacks that so many students carry today were originally designed for the military?
　　Market modification also means searching for increased usage among present customers or going for a different market, such as senior citizens. A marketer may re-position the product to appeal to new market sections.
　　Another product extension strategy is called product modification. It involves changing product quality, features, or style to attract new users or more usage from present users. American auto manufacturers are using quality improvement as one way to recapture（奪回） world markets. Note, also, how auto manufacturers once changed styles dramatically from year to year to keep demand from falling.

　 This is a part from US President Barack Obama’s speech on May 14 at Bamard College in New York.

　 … My last piece of advice – this is simple, but perhaps most important: 36 . Nothing worthwhile is easy. No one of achievement has avoided failure – sometimes catastrophic failures. But they keep at it. They learn from mistakes. They don’t 37 .

　 When I first arrived on this 38 , I was with little money, fewer options. But it was here that I tried to find my place in this world. I knew I wanted to make a difference, but it was 39 how in fact I’d go about it. But I wanted to do my part to 40 a better world.

But she didn’t quit. And she earned her degree, and made sure that 48 scholarships and hard work, my sister and I earned 49 .

And 50 , I met a woman who was assigned to advise me on my first summer job at a law firm. And she gave me such good advice that I married her. And Michelle and I gave everything we had to balance our careers and a 51 family. We made that marriage work.
