It’s almost ironic to call it a “history” of domain registrars since it’s been such a relatively short period of time since the internet has been in existence.
Yet a large portion of the people actively using the internet were not born when it first came to be. So this is the dirty story of domain registrars from the beginning.
As you may know, the internet started out as a US military effort to create a network that would be able to survive large-scale outages due to bombings, war, terrorism, or whatever the military could think up at the time. Sounds like a good topic for another article!
