Dot-com

Dot-com (dotcom or dot.com) companies were the collection of start-up companies selling products or services using or somehow related to the Internet. They proliferated in the late 1990s dot-com boom, a speculative frenzy of investment in Internet and Internet-related technical stocks and enterprises. The name derives from the fact that many of them have the ".com" Internet domain name suffix built into their company name.
