[Andrew Hume]

i will simply observe that when i joined bell labs in 1981, i was on the System III team. we certainly did internal releases under that name..

If I recall the argument in USG was many of the BSD tools were not better or even as good as what USG had already created.  But the USG folks did eventually add some of them to their stream because so many internal sites were already using them.  In particular, v, csh and col -- but there were others too and the argument was we have those tools covered already i.e. pg vs. more or se vs. vi
