I think www.domain.com evolved with www just being a commonly-chosen
subdomain name.  It's not at all required.  If fact, yahoo (to pick
an example out of the air) uses mail.yahoo.com, biz.yahoo.com,
and many others, all accessible via http://...

http is the protocol (that's what the "p" stands for) and is
not the only one used on the web.  If you poke around, you'll
find "ftp://domain.com" or (perhaps more commonly)
"ftp://ftp.domain.com" and the like.
