That’s part of it, yeah. But a lot of work was done in Universities as well, some through DARPA grant and some through university experiments. The one I got to witness as I got on in 1989 was the tail end of the merging of the University Unix systems experiments which utilized bang path (!’s where every computer in a chain was listed), vs IP system). The two networks were incompatible and efforts to make them talk to each other was tricky, as was merging a LOT of the various networks together. But they used the ARPA (military) and NSFNet (Science) as well as the IETF (Internet Engineering Task Force, still around) to standardize the various networks into the internet we ended up with.
