- E-reader growth: 6% to 12% of US adults from November 2010 to May 2011.
- Tablet growth: 5% to 8% in the same time period
Why the skepticism? The numbers just don't seem right. First of all, it's tough to get good numbers for the e-reader market, as the company that dominates, Amazon, refuses to divulge sales numbers (though it does say "Kindle is the bestselling e-reader in the world"). Second, almost all tablet sales are from Apple, and it reports strong growth. For example, reporting its results for the quarter that ended 12/25/10, the company said it had sold 7.3 million iPads. For the quarter that ended 3/26/11, the company reported selling 4.7 million iPads. While it looks like the drop was from lack of demand, it really had to do with the transition from the original product to the iPad2 and the inability to manufacture enough of the second-generation devices. Even with the hiccup, iPad sales should show greater consumer adoption in the Pew data.
For the e-reader market to verify and sustain the dramatic growth over tablets as seen in the Pew data, the only two viable candidates (Kindle and Nook) would have to sell way more devices than seem reasonable and the iPad would have to tank in sales. Yes, the price point for e-readers is much lower than tablets (think $130 versus $500), but estimates of sales of both devices don't seem to support the trend in the survey data. Some estimates of Kindle sales:
- 7.1 million Kindles in 2010 ... according to Barclays (via an All Things D article).
- 17.5 million Kindles in 2011 ... according to Citi Investment (via a TechCrunch article)
Compare that to estimates for iPad shipments:
- 32 million iPads for Apples 2011 fiscal year (9/10-9/11) ... from Needham (via this this Computerworld article)
- 14.4 million iPads in Q311 (calendar) ... from CLSA (via this Business Insider article)
Whatever numbers you believe, it doesn't make sense that e-readers have grown that much more than tablets in the time period reported by Pew ... or that the supposed trend will continue.
So what is the possible issue with the data? When asking about relatively new technology, survey questions can often be misinterpreted by consumers. I'd guess that (mostly) dedicated eReaders, such as the Kindle and Nook, and the e-reader capability of the iPad tablet is confusing to consumers. If, for example, a consumer uses iBooks on the iPad to read an eBook, will they answer the survey question about an e-reader accurately? Probably not.
All this may be moot in the end, as eBooks are taking off and the device will not matter so much in the future. Dedicated e-readers are adding a broader set of non-book functions, and tablets are likely to come down in weight, increase battery life, and drop in average selling price (ASP) price. In the end, the increasing popularity of reading electronic books is the key for authors and the publishing industry, not the type or brand of the device.
