PSINet

PSINet was an American internet service provider based in Northern Virginia. As one of the first commercial Internet service providers (ISPs), it was involved in the commercialization of the Internet until the company's bankruptcy in 2001 during the dot-com bubble and acquisition by Cogent Communications in 2002.

It was founded on December 5, 1989, and began offering services, including limited for-profit access to the Internet, on January 1, 1990, becoming one of the first companies to sell Internet connectivity.
