nine percent and counting…
From the Association of American Publishers:
Trade book sales (not including books for academic study) for the period of January-August 2010 had sales of $2.91 billion. eBook sales in the same period were $263 million.. E books for the period comprise 9.03% of total consumer book sales, compared to 3.31 percent at the close of 2009.
E book sales for January-August 2010 represented $263 million, compared to $89.8 million from January-August 2009, representing an overall increase for the category of 193% over the same period last year.
Yes, from a low base, but it’s catching on 🙂
And don’t forget, that’s unit sales – given that (notwithstanding ongoing shenanigans), ebooks are still mostly cheaper than print, there’s a fair chance that percentage sales of ebooks by unit are even higher.
