Groupware -- intentional group processes plus software to support them.
We were flabbergasted that when the book Groupware came out, we were not credited.
It seems that the origin of the term is unclear (i'm assuming we're talking about the origin of the term -- the original software that fit in the category is likely to be even murkier).

We first coined the term "groupware" in our research notes on October 4, 1978 during our work with Murray Turoff and S. Roxanne Hiltz on the Electronic Information Exchange System (EIES) at the New Jersey Institute of Technology. We wrote about it in an informal paper, "On CC and Citizen Participation," dated February 2, 1979, that we made available on EIES ("CC" = computer conferencing).
