Boston Computer Exchange was the world's first e-commerce company, and dominated electronic trading in used computers in the US in the 1980s. The Boston Computer Exchange, also called the BCE and BoCoEx, were in operation before the Internet became widely available to the general public. Their Bulletin Board System-based marketplace utilized Delphi online service as a platform for an on-line database of products where buyers and sellers bought, sold and traded computers. The company pioneered efforts to create a fully automated, on-line auction and trade systems for general commerce and eventually turned into an Internet-based business.
