Two major e-book reader manufacturers in the United States took price reduction measures on the 21st to deal with the increasingly fierce market competition. A new round of price war is expected to further promote the acceptance of e-book readers by mainstream consumers in the United States.

Barnes noble, a major U.S. bookseller chain, announced on the same day that the retail price of its 3G nook e-book reader has dropped from $259 to $199. A few hours later, Amazon, an online retail giant, announced that the price of its Kindle e-book reader had dropped from $259 to $189.
