eBay is one of Silicon Valley e-commerce giants. The company was founded in 1995, before shopping online became popular, and it survived the dot-com bubble of the early 2000s. It's a marketplace with an auction-like bidding system as well as a "Buy It Now" option for the fix-priced items. eBay doesn't own any of the stock, but it empowers customers and businesses to sell products through its platform. It's a place to search for a new pair of sneakers or a used vintage dresser at affordable prices.
