While tracking trends can be a useful tool in dealing with the unpredictable future, market research can be more of a problem than a help. Research does best at measuring the past. New ideas and concepts are almost impossible to measure. No one has a frame of reference. People don’t know what they will do until they face an actual decision.
The classic example is the research conducted before Xerox introduced the plain-paper copier. What came back was the conclusion that no one would pay five cents for a plain-paper copy when they could get a Thermofax copy for a cent and a half. Xerox ignored the research, and the rest is history.

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.

successful positioning requires consistency. You must keep at it year after year.
