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.
