People who built the network
Researchers, engineers, operators, and community leaders whose choices shaped the internet's open architecture.
BTW Media Editorial Collection
History of the Internet
The internet was not born as a finished system. It was built across decades by researchers, engineers, operators, institutions, and communities who chose openness, interoperability, and shared stewardship before the world knew what the network would become.
History of the Internet is BTW Media's editorial archive of the people, protocols, institutions, and turning points that shaped the global network.
This collection brings together interviews, profiles, source-backed reporting, and historical analysis about the builders and witnesses of the internet age.
This page follows how individual decisions, technical principles, public institutions, and regional communities became civilization-scale infrastructure.
For the people recorded here, this is a record of contribution. For readers, it is a map of how the internet became one of humanity's shared systems.
