FRS
 //, n.,obs.

    [obs.] Abbreviation for ?Freely Redistributable Software? which entered
    general use on the Internet in 1995 after years of low-level confusion over
    what exactly to call software written to be passed around and shared
    (contending terms including freeware, shareware, and sourceware were
    never universally felt to be satisfactory for various subtle reasons). The
    first formal conference on freely redistributable software was held in
    Cambridge, Massachussetts, in February 1996 (sponsored by the Free Software
    Foundation). The conference organizers used the FRS abbreviation heavily in
    its calls for papers and other literature during 1995. The term was in
    steady though not common use until 1998 and the invention of open source,
    after which it became swiftly obsolete.
