Domain tools declare that .coms have now reached the magic figure.
We sort of agree based on other statistics hosterstats quote a 1st January figure of 99.3m and the average increase over the last couple of months was 0.5m (and the last quarter of the year is usually the least active time of the year domainwise).
To get some worldwide perspective we have roughly charted the top 20 domains as at the end (in certain cases 3rd quarter) of 2011. Some registries only report information quarterly and also certain information was unavailable from hosterstats database. There are another 30 odd top level domains with a further 15.4 million ish domains.
The top 20 cover over 90% of the total domain registrations.
