When it comes to e-book pricing, publishers are the ones paying the price

The number of books sold on Amazon in its first three weeks is down almost 30 percent compared with the same period last year, according to data released by the company.

Amazon is a dominant player in the e-reader market, but it’s not alone, according of the data.

For instance, rival Barnes & Noble, which is backed by Apple, was the largest seller last year with about 5 million books sold, while Nook, Kindle and iPad accounted for just 2.5 million.

Barnes & Norris is the most valuable publisher with an estimated $11.7 billion in sales.

Apple is the second-most valuable, with $11 billion in annual sales.

The data also show Amazon is not the only e-readers market leader.

Google dominates the smartphone market, with about 3.7 million smartphones sold last year.

Amazon’s smartphone sales have fallen more than 40 percent from the same time last year as the company’s ebook business is down nearly 30 percent. 

Google, by the way, has been aggressively buying up book publishers.

Last month, it bought Penguin for $970 million.
