Still waiting for the hockey stick: IDPF Q2 e-book numbers show growth accelerating

IDPF final Q2Following up on Monday’s analysis of the growth of sales in e-books, the IDPF has released final Q2 e-book sales figures, which totaled $37.6 million. It shows accelerated, not exponential growth. That makes the resolution of early problems with e-book publishing, such as providing customers assurance their e-book files will be readable across devices over time all the more important, because any backlash now will cut off growth. It will be interesting to see if the Amazon 1984 event will stunt growth in sales.

Growth year-over-year reached 224.14 percent in Q2, slightly above the estimate provided here. More encouraging is the quarter-to-quarter growth of 45.75 percent, which is only a slight decline compared to Q1 growth of 53.57 percent. In previous years, the second quarter’s growth has fallen off more steeply from Q2, so the numbers suggest that growth is established based on the wider adoption of devices.

Nevertheless, the e-book market growth remains well below the exponential increases everyone would like to see. It’s a delicate time for this market.
