Wikipedia:
eBay Inc. (/ˈiːˌbeɪ/ EE-bay, stylized as ebay) is a multinational e-commerce corporation, facilitating online consumer-to-consumer and business-to-consumer sales. It is headquartered in San Jose, California. eBay was founded by Pierre Omidyar in 1995, and became a notable success story of the dot-com bubble. Today eBay is a multibillion-dollar business with operations in about 30 countries.

The company manages eBay.com, an online auction and shopping website in which people and businesses buy and sell a broad variety of goods and services worldwide. In addition to its auction-style sales, the website has since expanded to include "Buy It Now" shopping; shopping by UPC, ISBN, or other kind of SKU number (via Half.com); online classified advertisements (via Kijiji or eBay Classifieds); online event ticket trading (via StubHub); and other services. It previously offered online money transfers (via PayPal, which was a wholly owned subsidiary of eBay from 2002 until 2015). The website is free to use for buyers, but sellers are charged fees for listing items after a limited number of free listings, and again when those items are sold.
