The dispute was backed by the Amazon Cooperation Treaty Organisation (ACTO), a group promoting the development of the Amazon Basin. Its member states include Brazil, Peru, Bolivia, Colombia, Ecuador, Guyana, Suriname, and Venezuela. [...]
Amazon had tried for years to get ACTO to drop their complaint. At one point, the company had even offered $5 million in gift cards to Brazil and Peru, the ACTO member states who originally filed the complaint, to no avail. [...]
When Amazon applied to run the ".amazon" domain extension, Brazil and Peru filed a formal complaint with ICANN. The complaint stated that giving Amazon the rights to the extension would "prevent use of this domain for purposes of public interest" and argued that ".amazon" should instead serve regions of the Amazon in South America.
ICANN, has approved of Amazon's proposal to run the top level domain name extension ".amazon" after a 7 year dispute with more than a half dozen countries.
