    1.25 +In 1977, Stockton Gaines and Norman Shapiro of the \s-1RAND\s0 Corporation
    1.26 +came up with a concept for a new electronic mail system.
    1.27 +Till then, \s-1RAND\s0 had used \s-1MS\s0 (``mail system''),
    1.28 +which was monolithic.
    1.29 +In 1978 and 1989, Bruce Borden implemented the concept \(en
    1.30 +this was the birth of \s-1MH\s0.
    1.31 +.PP
    1.32 +Since then, \s-1RAND\s0, the University of California at Irvine and
    1.33 +at Berkeley, and several others have contributet to the software.
    1.34 +However, it's core concepts remained the same.
    1.35 +In the 90s, the development of \s-1MH\s0 slowed down.
    1.36 +Richard Coleman started with \fInmh\fP, the new mail handler,
    1.37 +in 1997 to improve \s-1MH\s0, especially in regard of modern emailing.
    1.38 +Today, nmh is developed by various people on the internet.
