  1. rn

    rn is a news client written by Larry Wall and originally released in 1984. It was one of the first newsreaders to take full advantage of character-addressable CRT terminals. Previous newsreaders, such as readnews, were mostly line-oriented and designed for use on the printing terminals which were common on the early Unix minicomputers where the Usenet software and network originated. Later variants of the original rn program included rrn, trn, and strn.
