This number may appear to be disappointingly small (ebooks were 21.67% of US market in 2012), but let me put it into perspective
Consider for a moment the growth of the US ebook market in the early Kindle years. According to the AAP, ebook sales made up 1.18% of the US book market in 2008 and 3.17% in 2009.
That 2009 figure is particularly important because it represents the US market when it was only 2 years into the Kindle era; that is where Germany is right now.
While Amazon did launch an international Kindle in 2009, Amazon, Kobo, and other ebooksellers only really started investing in the German ebook market in 2011. Kobo launched in Germany in July 2011, and Amazon launched a local Kindle Store there in April 2011.
Germany is really only 2 years into the Kindle era, so it should come as no surprise that the ebook market share is still as small as it is.
And given the recent investments in this ebook market, it is bound to grow. Most of the major ebooksellers (Apple, Google, Amazon) and Kobo have opened ebookstores in Germany in the past couple years, and earlier this year a local coalition, Tolino, formed and launched a new shared ebookstore platform and ereader.
But in spite of my hopes for growth, the German ebook market is still facing a serious supply issue. The selection of available titles is still limited, with GfK reporting that only 54 percent of all new titles and 29% of publisher's backlist available as ebooks. Less than half of the ebooks that a consumer might want to buy are available digitally, and that is likely dampening the ebook adoption rate.
