Studies of industry emergence, like studies of entrepreneurship generally, have tended to emphasize success rather than failure. This is for perhaps two important reasons: 1) data is easier to find for successes, and 2) successful examples would seem necessarily to hold the key ingredients for future entrepreneurs, if only those key ingredients could be isolated. But by selectively studying success without comparison to failure, it is difficult to strongly identify those conditions and variables necessary>/em>, and impossible to understand important relationships among sets of key variables.
