The Google search engine (a take off on googol, which is 1 followed by 100 zeros) has some interesting search functions, one of which is the site: parameter.
Using this, you can search for a word or phrase, but limit the search to either one site, or one gTLD / ccTLD.
Using the common word "contact", (which is on most every web site somewhere, maybe index or contents would also work), I found the folowing results, which gives a relative indication of the number of sites for each gTLD / ccTLD.
site:.com "contact" 10,800,000 hits
site:.org "contact" 7,520,000 hits
site:.net "contact" 4,640,000 hits
site:.us "contact" 2,970,000 hits
site:.info "contact" 384,000 hits
site:.biz "contact" 173,000 hits
site:.com "home" 9,390,000 hits
site:.org "home" 6,680.000 hits
site:.net "home" 4,320,000 hits
site:.us "home" 3,090,000 hits
site:.info "home" 519,000 hits
site:.biz "home" 234,000 hits
The big numbers for .us reflect that it has been around for almost as long as the gTLD's, but in level three format, such as www.kenedy.k12.ny.us for Kennedy Central Schools in NY.
The first actual ccTLD was the .us ccTLD, created on 2/15/1985.
Individuals could always register their own .us ccTLD name, for free. The format would be for example john.postal.los-angeles.ca.us. These are still free, for life I guess, from Neustar.
Users would contact the local ISP that handled delegated subdomains (Outdated list here, Neustar handles this now: http://neustar.us/register/delegated_subdomains.txt), and request an application, fill it in, and in a few weeks, a free domain name would arrive.
This process accounts for most of the 3 million+ .us domain names in active use, most for state, county and local govenment, community colleges, schools, etc.
