What makes a bestseller a bestseller?

Search-engines-web.com writes “A Mercury News article reports on a research teams new theory of how bestseller books are made:

‘They found that top sellers tend to reach their sales peak in one of two ways. As predicted, many get there because of so-called exogenous shocks: a major media announcement, a celebrity endorsement, a dignitary’s death. In these cases, the instant rise in sales is followed by a fairly quick decline.

Other books inch their way to the top over many months, helped by cascades of tiny “endogenous shocks” such as a friend’s recommendation. A prime example is “Divine Secrets of the Ya-Ya Sisterhood,” which made the bestseller list two years after publication without a major ad campaign. How? It caught on in book-discussion clubs and spurred women to form their own “Ya-Ya Sisterhood” groups.

Such books descend the rankings more slowly than those propelled by exogenous shocks. Much more than a one-time radio announcement or newspaper review, “when people talk to each other, it sticks to the network much more,” Gilbert said.”
