A Cyberauction House is an online marketplace where buyers and sellers can conduct auctions for goods and services. The most well-known example of a Cyberauction House is eBay, which was founded in 1995 and has become one of the largest online marketplaces in the world. On eBay, buyers can bid on items and sellers can list items for auction. Buyers and sellers can also communicate with each other through the platform. eBay has revolutionized the way people buy and sell goods online, making it easier and more convenient than ever before.
