eBay was founded by Pierre Omidyar in 1995, and became a notable success story of the dot-com bubble. eBay is a multibillion-dollar business with operations in about 30 countries, as of 2011.The company manages eBay.com, an online auction and shopping website in which people and businesses buy and sell a wide variety of goods and services worldwide. 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.

In addition to its original auction-style sales, the website has since evolved and expanded to include "Buy It Now" shopping; shopping by UPC, ISBN, or other kind of SKU number (via Half.com); online classified advertisements , 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 to 2015).

The AuctionWeb was founded in California on September 3, 1995, by French-born Iranian-American computer programmer Pierre Omidyar as part of a larger personal site.[5] One of the first items sold on AuctionWeb was a broken laser pointer for $14.83. Astonished, Omidyar contacted the winning bidder to ask if he understood that the laser pointer was broken. In his responding email, the buyer explained: "I'm a collector of broken laser pointers."

The company officially changed the name of its service from AuctionWeb to eBay in September 1997. Originally, the site belonged to Echo Bay Technology Group, Omidyar's consulting firm. Omidyar had tried to register the domain name echobay.com, but found it already taken by the Echo Bay Mines, a gold mining company, so he shortened it to his second choice, eBay.com.
