Beyond reading articles touting the eBook phenomenon, I have personally witnessed the shift in book sales from print to eBooks. In the first half of 2011, 72% of my book sales were eBooks. This contrasts with eBook sales of 33% for the first half of 2010. This is not a shift, this is a stampede.
What does this mean for authors? It means authors need to reassess the timing of their promotional efforts. For example, I'm wondering how the heck do I get to readers on Christmas day, Father's Day, Mother's Day, and on their birthday?
