"Any new publisher will need to understand the paths to market. Yes, Amazon gets more than half of the US ebook sales and Barnes & Noble gets half of the rest. But it isn’t that way on every book, ignoring the others leaves a big chunk of the market unexploited, and things are changing quickly. Amazon’s market share has dropped by a huge percentage in the past two years.) OverDrive is the primary path to libraries. Ingram aggregates many independent stores. Baker & Taylor is opening up markets among mass merchants. Kobo is as important in Canada as B&N is in the US and works in markets all over the world. Google has the ebook ecosystem making the most serious penetration of independent book retailers. Sony is about to introduce new devices that could increase their importance. And Apple is doing its best to dominate sales to its own device holders, who constitute a large wedge of the ebook customer pie."
