What is "psinet"

PSINet, based in Northern Virginia, was one of the first commercial Internet service providers (ISPs) and 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 officially 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.
