The top-level international commercial domain.

*.com is technically reserved for commercial ventures which have an international presence or client base.

Using *.com for strictly national business concerns is tantamount DNS banditry - it denies valid domains to those who have a better use for them. Unfortunately, *.com has become something of a status symbol so that every corner shop or old lady knitting sweaters think they need one to claim a valid net-presence. Hopefully, education will rememdy this. Before the DNS runs out.
