Bestseller lifespan has shortened

JET writes “Lulu.com has an article on the lifespan of a best seller.”

The average number of weeks that a new No. 1 bestseller stayed top of the hardback fiction section of the New York Times Bestseller List has fallen from 5.5 in the 1990s, 14 in the 1970s and 22 in the 1960s to barely a fortnight last year — according to the study of the half-century from 1956-2005. In the 1960s, fewer than three novels reached No. 1 in an average year; last year, 23 did.
