I mentioned Flint's Law on this blog a couple weeks back (here). Today I came across another piece of evidence that proves it. Here's an excerpt from a blog post by Nathan Henrion:
One of our free titles was the #1 download on Amazon for the entire month of February. The subsequent sales of books 2 and 3 in the series increased by a rate of 20 to 1. For this series, digital sales are approaching 20% of the total product sales distribution and growing. With the visibility of the digital sales on Amazon, we have seen a substantial increase in print sales to the brick and mortar book chains. In this one instance, digital is driving print sales.
Is this even news anymore?
Update: I went back to add links to some of the news stories that mention this, and guess what: the several sites that inspired me to write this were in fact taking the exact same position, and had done so repeatedly. I'm late to the party here.
