EBay was founded in 1995 by Pierre Omidyar as an online marketplace that allows individuals and businesses to buy and sell a variety of goods. It has since grown into a multinational corporation localized in over 30 countries. EBay's decentralized business model gives users independence to sell any products without approval, while EBay maintains oversight of the platform. This structure provides incentives for users to update their listings and adapt to consumer demand. Key competitors of EBay include Amazon, Yahoo, Google, and Overstock.com.
