For example, who had need of the personal computer before it was introduced by Apple in the 1970s? The personal computer was seen in the context of a hobby that relative few “hackers” enjoyed. No one really envisioned that the PC would take on the demand significance it did. In the 1970s IBM predicted there would be fewer than 150000 PCs would-wide by the end of the century. In this illustration we see that technology literally created its own demand and opportunity.
