  Surely there were Mailing Lists prior to the
existence of the Internet,
 yes? 
 Absolutely. They started on the ARPANet, fairly early on.
 E.g. SF-Lovers (one of the first 'non-mission related' mailing lists) started
 in September, 1979, and MsgGroup (an 'official-busines-related' one)
 considerably earlier, in June 1975. Header-People started at about the same
 time, but alas, we have lost the first two volumes of the archives, so I don't
 know exactly when. 
Multi-user communication systems of a somewhat different architecture are even older:
"Notes files" on the PLATO system.
