eBay, is a global online auction and trading company, and was one of the first companies to create and market an Internet Web site to match buyers and sellers of goods and services. The company, which caters to individual sellers and small businesses, is a market leader in e-commerce worldwide. It is headquartered in San Jose, California. Customers can participate in Web sites set up within their own country or use one of the company’s international sites. There are eBay websites for both the U.S. and Canadian markets, most European countries, and several countries in Asia. Latin American websites are operated in association with Mercado Libre, an e-commerce provider running similar operations. Although auctions constitute the bulk of eBay sales, fixed-price sales also constitute a significant share of transactions.
