Alibaba Group Holding Limited is a Chinese e-commerce company that provides consumer-to-consumer, business-to-consumer and business-to-business sales services via web portals. It also provides electronic payment services, a shopping search engine and data-centric cloud computing services. The group began in 1999 when Jack Ma founded the website Alibaba.com, a business-to-business portal to connect Chinese manufacturers with overseas buyers. In 2012, two of Alibaba's portals handled 1.1 trillion yuan ($170 billion) in sales. Suppliers from other countries are supported (with more stringent checks than for Chinese companies), but the company primarily operates in the People's Republic of China (PRC). At closing time on the date of its initial public offering (IPO), 19 September 2014, Alibaba's market value was US$231 billion. However, the stock has traded down and market cap was about $212 billion at the end of December 2015.
