Dangdang

E-commerce China Dangdang Inc. (), known as Dangdang, is a Chinese electronic commerce company, founded by Peggy Yu and Li Guoqing in 1999. It is headquartered in Beijing and its main competitors are Amazon.cn (or Amazon China, formerly Joyo.com) and JD.com (or Jingdong, formerly 360buy.com). The competition escalated into a price war in December 2010, with each retailer marking down a wide range of items, especially books. DangDang made an IPO on the NYSE in November 2010, estimated at approximately US$1 billion.
