freeware
n. Free software, often written by enthusiasts and
distributed by users' groups, or via electronic mail, local
bulletin boards, USENET, or other electronic media. At one
time, `freeware' was a trademark of Andrew Fluegelman, the author
of the well-known MS-DOS comm program PC-TALK III. It wasn't
enforced after his mysterious disappearance and presumed death
in 1984. See shareware.
