Harvard marketing professor Anita Elberse has conducted a study which seems to reveal that customer purchasing behavior with regard to hits is the same online as it is offline. In her Harvard Business Review article, she reports:
For Chris Anderson, the strategic implications of the digital environment seem clear. “The companies that will prosper,” he declares, “will be those that switch out of lowest-common-denominator mode and figure out how to address niches.” But my research indicates otherwise. Although no one disputes the lengthening of the tail (clearly, more obscure products are being made available for purchase every day), the tail is likely to be extremely flat and populated by titles that are mostly a diversion for consumers whose appetite for true blockbusters continues to grow. It is therefore highly disputable that much money can be made in the tail. In sales of both videos and recorded music—in many ways the perfect products to test the long-tail theory—we see that hits are and probably will remain dominant. That is the reality that should inform retailers as they struggle to offer their customers a satisfying assortment cost-efficiently. And it’s the unavoidable challenge to producers. The companies that will prosper are the ones most capable of capitalizing on individual best sellers.
Chris Anderson, the author of the book The Long Tail, responds to the article on his blog. He argues that her different results are due to differing definitions of “head” and “tail”.
