"In its drive for profitability, Amazon did not raise retail prices; it simply squeezed its suppliers harder, much as Walmart had done with manufacturers. Amazon demanded ever-larger co-op fees and better shipping terms; publishers knew that they would stop being favored by the site’s recommendation algorithms if they didn’t comply. Eventually, they all did. (Few customers realize that the results generated by Amazon’s search engine are partly determined by promotional fees.) Sales meetings in Seattle were now all about payments, not new books, and the size of orders was predicated on algorithms, rather than on the enthusiasm of the publishers’ sales staff and Amazon’s own buyers, who were rebranded as “inventory managers.” Brad Stone describes one campaign to pressure the most vulnerable publishers for better terms: internally, it was known as the Gazelle Project, after Bezos suggested “that Amazon should approach these small publishers the way a cheetah would pursue a sickly gazelle.” (Company lawyers later changed the name to the Small Publisher Negotiation Program.)"
