eBay Inc. is an American Internet company that 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. A majority of the sales take place through a set-time auction format, but subsequent methods include a substantial segment of listings in the "Buy It Now" category.

In addition to its original U.S. website, eBay has established localized websites in thirty other countries. eBay Inc. also owns PayPal, Skype (to be sold soon), StubHub, Kijiji, and other businesses.

The online auction website was founded as AuctionWeb in San Jose, California, on September 3, 1995, by French-born Iranian computer programmer Pierre Omidyar as part of a larger personal site that included, among other things, Omidyar's own tongue-in-cheek tribute to the Ebola virus. In 1997, the company received approximately $5 million in funding from the venture capital firm Benchmark Capital.

The very first item sold on eBay 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 frequently repeated story that eBay was founded to help Omidyar's fiancée trade Pez Candy dispensers was fabricated by a public relations manager in 1997 to interest the media. This was revealed in Adam Cohen's 2002 book, The Perfect Store, and confirmed by eBay.
