What is the oldest three letter .com domain? HP.com.
Registered on March 3, 1986, HP.com was also the 9th registered domain name, almost a full year after Symbolics.com!
HP.com was registered to computer manufacturing giant, Hewlett-Packard, an American multinational information technology company headquartered in Palo Alto, California, that developed and provided a wide variety of hardware components as well as software and related services to consumers, small and medium-sized businesses (SMBs) and large enterprises, including customers in the government, health and education sectors.
The company was founded in a one-car garage in Palo Alto, California by Bill Hewlett and David Packard in 1939, and initially produced a line of electronic test and measurement equipment.
On November 1, 2015, Hewlett-Packard changed its name to HP Inc. and spun off Hewlett Packard Enterprise as a new publicly traded company.
HP.com is an active web site of the company, and there is no indication that it will stop being used, or be sold in the near future to the Chinese!
