eBay is an American multinational e-commerce corporation established in 1995 that operates online marketplaces where goods and services are bought and sold. It has over 300 million active buyers globally. eBay segments its markets geographically and demographically, with the majority of users being between 35-55 years old with an average income of $50k-$75k annually. eBay's business model involves sellers listing items for sale through auctions with buyers bidding, or through fixed-price listings. It generates revenue through insertion fees from sellers and a percentage of final sale prices. While eBay dominates the online auction market, it faces threats from increasing competition and potential issues with fraud and privacy that it works to address through security and dispute resolution programs
