An interesting data analysis scenario
Had PowerPoint been around 150 years ago, Thoreau might have warned us to beware not only of enterprises that require new clothes, but also of those that require new paradigms.
A book from 2006, "The Long Tail," was one of those that appear periodically and demand that we rethink everything we presume to know about how society works. In this case, the Web and its nearly unlimited choices were said to be remaking the economy and culture. Now, a new Harvard Business Review article pushes back, and says any change occurring may be of an entirely different sort.
Since appearing two years ago, the book has been something of a sacred text in Silicon Valley. Business plans that foresaw only modest commercial prospects for their products cited the Long Tail to justify themselves, as it had apparently proved that the Web allows a market for items besides super-hits. If you demurred, you were met with a look of pity and contempt, as though you had just admitted to still using a Kaypro.
That might now start to change, thanks to the article (online at tinyurl.com/3rg5gp), by Anita Elberse, a marketing professor at Harvard's business school who takes the same statistically rigorous approach to entertainment and cultural industries that sabermetricians do to baseball.
Mr. Anderson responded on his Long Tail blog, thelongtail.com, saying much of the difference between his analysis and hers involved how hits and non-hits, or "head" and "tail" in the book's lingo, are measured. Aside from that, he was generous in praising the article, and said he welcomed the sort of rigorous scrutiny the theory was getting.
(p.s. I still have my trusty Kaypro, from ~25 years ago, but I don't use it anymore...)
