The ARPANET was built in the late 1960s, grew during the 1970s and 1980s, and was the backbone network that led to the evolution of today's Internet. Dr. Crocker discussed the formative period which led to the creation of the RFCs and the founding of the Network Working Group (precursor to today's Internet Engineering Task Force). He gave us the flavor of the technical and political landscape and shared his views of what went right and where the mark was missed.
