The year-end totals for 2012 e-book sales are in the books (har, har), and the results are net revenues of $1.54 billion ($1,540M), an increase of 41% over 2011 figures. (Note that means that 2011 figures actually surpassed $1 billion, even though they were reported just under that figure a year ago. The AAP figures always seem to be adjusted upwards over time, presumably adding late-reporting sales.) While a 41% increase is nothing to sneeze at, it is a marked slowdown compared to the triple-digit growth rates of the previous three years:

• 2002:   $2.1M
• 2003:   $6.0M   (185.7% increase)
• 2004:   $9.3M   (55.0% increase)
• 2005:   $16.0M   (72.0% increase)
• 2006:   $25.2M   (57.5% increase)
• 2007:   $31.7M   (25.8% increase)
• 2008:   $61.3M   (93.4% increase)
• 2009:   $169.5M   (176.5% increase)
• 2010:   $441.3M   (160.4% increase)
• 2011:   $1,092.2M   (147.5% increase)
• 2012:   $1,540.0M   (41.0% increase)

Print books did better than expected, but still declined slightly, from about $5,338M to about $5,289M. Buoyed by the growth in e-books, overall publisher revenues increased 6.2%, from about $6,431M to $6,829M.

E-books accounted for 22.55% of publisher revenue in 2012, a moderate increase from 16.98% in 2011. For comparison, e-book revenue as a percentage of the total was only 0.05% in 2002, increasing as a percentage by almost 500x in a decade:

• 2002:   0.05%
• 2003:   ???
• 2004:   ???
• 2005:   ???
• 2006:   0.50%
• 2007:   ???
• 2008:   1.18%
• 2009:   3.17%
• 2010:   8.32%
• 2011:   16.98%
• 2012:   22.55%

It seems clear that the days of e-book sales doubling and tripling are over, based on these 2012 figures, the fact that December sales grew even slower than overall 2012 sales (up only 20% from Dec 2011), and the fact that nothing can double or triple forever, especially as a percentage of overall sales.

So, how did I do on my predictions from a year ago? Back then (when 2011 sales figures came in), I predicted that:

Of course, nothing can double forever, and my early prediction is that 2012 e-book sales will fail to double from this year’s numbers — maybe up 50% or so to about $1,500M (one and a half billion).

With the actual figure coming in at $1,540M, that means my prediction was within 3% of the actual number … just like my prediction for 2011 sales made two years ago. =)

Note: between an all-encompassing “day job” and the arrival of our first child last month, I haven’t had nearly enough time to keep up with publishing industry trends or e-book sales stats as I used to — let alone having time to then blog about those things. But I’ll go ahead and keep up the tradition and make a prediction for 2013 e-book sales anyway: based on the lack of innovation in e-readers (yes, we have lighted e-readers, but no color or flexible screens yet) and the saturation of the market, I predict that e-book sales will continue to slow their rate of increase, perhaps increasing another 20-25% over this year’s sales figures, which would put 2013 e-book sales between $1.75 and $2 billion.

Looks like a big month for e-books in January 2012, although the Association of American Publishers went and changed up their system on us, growing from collecting data from 90 publishers up to 1,150. While this should give a more comprehensive and accurate picture of sales, it also makes comparisons with prior data more difficult.

On the plus side, they released a good amount of granular detail for both January 2011 and January 2012. The summary: e-book sales for January 2012 total a whopping $128.8M, shattering the old record of $90.3M from Feb 2011 (more on that next month). This compares to (revised, apples-to-apples) sales from January 2011 of $73.2M, or a 56.8% increase. Perhaps most impressively, e-books totaled 26.7% of all book sales (print, e-book, and audiobooks) for the month.

The details from Jan 2012:

Compare to Jan 2011:

The AAP must have some other figures they don’t include in the numbers above, because they list total Jan 2012 sales at $503.5M and Jan 2011 at $396.0M, a healthy 27.1% increase from last year.

Some highlights that jump out:

1. Mass-market paperback sales continue their decline (now down below 1/3rd that of e-books — it wasn’t that long ago that e-books passing MM paperbacks seemed like a big deal).
2. Adult e-book sales are up almost 50% from last year, and young adult e-book sales are up nearly six times last year’s figures, due no doubt to the increasing popularity of color tablets (like the Kindle Fire and Nook Tablet) that allow for interactive children’s e-books.
3. Young adult sales in general did very well — I wonder if much of the difference can be attributed to the mega-popular Hunger Games books.

January 2012 e-book sales: $128.8M

As explained above, don’t look at this chart and take the comparisons to earlier months as gospel, as the AAP’s new methodology makes month-to-month comparisons inexact. Last year, Jan 2011 sales were reported as $69.9M; this month (retroactively using the new methodology), they were adjusted upward to $73.2M. But a total of $128.8M in e-book sales is still a significant increase from any previous months, putting e-books on pace for $1.5 billion in sales for the year.
