The “.com” top-level domain (TLD) was among the first set of TLDs introduced in January 1985 when the Domain Name System (DNS) was implemented for the internet. Initially, it was intended for commercial organizations, as the name suggests. However, over time, the restrictions were lifted, and “.com” became available for general purposes. It has since grown to be the largest and most recognizable TLD globally, currently used by a significant percentage of all websites. The popularity of “.com” played a central role in the “dot-com bubble” of the late 1990s. Today, Verisign operates the “.com” registry under the ultimate jurisdiction of U.S. law, and registrations are processed through ICANN-accredited registrars.

Here is the continuation of the list of the first .com domain names registered, from 101 to 200, along with their registration dates and the registering organizations. This list continues from where the previous list ended in November 1987 and extends into 1988 and beyond.

Note: There might be some re-registrations or different entities with the same name appearing in the early registration records. The dates provided are the registration dates as recorded.

The initial growth of .com domain registrations was relatively slow in the early years, primarily driven by research institutions and large corporations. The process was also less formal and more restricted compared to today’s open registration system. The introduction of fees in 1995 and the subsequent commercialization of the internet led to an explosive growth in .com domain name registrations. Today, “.com” remains the most popular and widely recognized top-level domain globally.
