Alibaba is China’s — and by some measures, the world’s — biggest online commerce company. Its three main sites — Taobao, Tmall and Alibaba.com — have hundreds of millions of users, and host millions of merchants and businesses. Alibaba handles more business than any other e-commerce company.
Alibaba is the most popular destination for online shopping, in the world's fastest growing e-commerce market. Transactions on its online sites totaled $248 billion last year, more than those of eBay and Amazon.com combined.
