Customers don't want a 1/4-inch drill; they want a 1/4-inch hole.

So said Ted Levitt and his article, "Marketing Myopia," stands as a classic.

In my own experience at Hewlett-Packard Medical Electronics, our engineers were positively charmed by their inventions, but what the savvier marketing folks understood was that the patient's vital signs were not the central reason the equipment was purchased - although it was very important - but more to the point, the physicians and staff wanted a trend line.

Some years ago there was the "CB craze." The Citizen's Band radios were all the rage, especially among truckers.

There was even a hit single about truckers called "Convoy" where the CB radio was a "star."

Hollywood on the run.

Hollywood is worried, although they have not yet had a full-blown panic attack. Their bedrock market - the one they have always taken for granted - is eroding beneath their feet. Generation X, is growing up and their tastes have changed.

Ten years before that, most computers with any power were the size of a refrigerator and word processing was something that required a special set of hardware - and Wang was its name. Color laser printers, digital cameras, flat panel monitors, search engines, web cafes - the concepts ranged from Buck Rogers to the incomprehensible.
