The government laid the groundwork, but the money didn't come until
after the government got out of the way.
Agreed. There was no clear transition between the government operated
research internet and the current commercial version. The closest
approximation was when NSFnet (National Science Foundation) network,
closed down, and was replaced by an assortment of privately funded
backbone providers. The big difference was that the private backbones
allowed and encouraged redistribution of bandwidth and content, while
this was forbidden by the contractors providing service to NSFnet.
That allowed the creation of thousands of mom and pop small ISP's that
could now sell internet access to the GUM (great unwashed masses). At
the time, NSFnet was on 56Kbits/sec DS0 lines and the internet was
almost entirely usenet and various BBS mutations. User access was by
slow dialup. While the commercialization of the internet followed
immediately there after, it would never have happened if the
government had continued NSFnet and redistribution continued to be
prohibited. Unfortunately the first real example of commercial
advertising on the internet were the green card spammers:

Depending on your point of view, it's been down hill (or up hill) ever
since.
