Amazon rarely buys paper books electronic
According to the report of the most popular online store in the world, in the spring, for every 143 books for the Kindle reader, there were only 100 ordinary hardcover books. In June, the gap widened to 180 electronic versus 100 paper books.
Breakthrough? Well, not quite. The fact is that Amazon statistics do not take into account paperback pocket editions and some other categories of literature. So in general, paper books are still more popular than electronic ones.
However, the general trend of the paperback clause does not cancel. Electronic literature is gaining popularity. This is confirmed by the sales of the Kindle DX, which continue to grow, despite the fierce competition from the iPad.
