A fad is a wave in the ocean, and a trend is the tide. A fad gets a lot of hype, and a trend gets very little. Like a wave, - Al Ries

Most marketing mistakes stem from the assumption that you’re fighting a product battle rooted in reality.

You see this in the toy business. Some owners of hot toys want to put their hot toy name on everything. The result is that it becomes an enormous fad that is bound to collapse. When everybody has a Ninja turtle, nobody wants one anymore. The Ninja turtle is a good example of a fad that collapses in a hurry because the owner of the concept got greedy. The owner fans the fad rather than dampening it. On the other hand, the Barbie doll is a trend. When Barbie was invented years ago, the doll was never heavily merchandised into other areas. As a result, the Barbie doll has become a long-term trend in the toy business.

Futurist Faith Popcorn goes even further. By the year 2010, she predicts, 90 percent of all consumer products will be home-delivered. “They’ll put a refrigerator in your garage and bar code your kitchen. Every week they’ll restock your favorites, without your ever having to reorder. They’ll even pick up your dry cleaning, return your videotapes, whatever you need.
