uucp(1) General Commands Manual
NAME
uucp - Unix to Unix copy
SYNOPSIS
uucp [ options ] source-file destination-file
uucp [ options ] source-file... destination-directory
DESCRIPTION
The uucp command copies files between systems. Each file argument
is either a pathname on the local machine or is of the form
system!path
which is interpreted as being on a remote system. In the
first form, the contents of the first file are copied to the
second. In the second form, each source file is copied into
the destination directory.

I seem to recall that Rick helped fund the transition of Usenet from UUCP to TCP/IP by giving away 56kb modems to hosts that applied for domain names. I *think* (memory is fuzzy here as this wasn't something I directly worked with), that most of the modems eventually transitioned from UUCP dialup to permanent link IP.
