Amazon, as one of the largest e-commerce businesses in the United States, has been involved in controversies that point to its censorship-like actions. In 2010, Macmillan Publishers, along with some other publishers, asked Amazon to increase the prices of the electronic books it offered for sale on Amazon by 50% from $9.99 to $15, after obtaining permission from Apple to raise its prices, who was more lenient in allowing the publishers to determine prices themselves. Amazon disagreed with its proposal, and they didn't reach a consensus on how to deal with this problem. Amazon later removed all books published by Macmillan Publishers, including electronic books and physical books, from the website. Later, Amazon "surrendered" to Macmillan Publishers' request of price increase.
