Network Working Group
40 years ago a group of researchers was funded by DARPA to study packet-based communications, one part of which was the Network Working Group. Part of this group has since become the IRTF's End2End Research Group, and the rest of the functions have devolved on the IAB and the IETF. The Network Working Group, as such, has not been functional for nearly 20 years.
I personally would like to see us stop attributing documents to them. The world has long since moved on, and those who don't recognize it date themselves.
