four books a year? no wonder the teabaggers got into power

Kobo has chased the “heavy reader” segment in particular. Book buying resembles many consumer markets, where the 80/20 rule operates: 20% of the customers buy 80% of the product. So by Kobo targeting heavy users, they can efficiently sell a larger volume. It’s difficult to get comparable figures internationally, but according to management consultant (and my colleague) Brian O’Leary, the average U.S. consumer buys about 4 books per year, and the frequent buyer purchases 12 to 45 books per year. Humphrey reports that his readers via a Kobo device buy on average four books per month, or 48 per year.
