Who Invented The First Chat Room? Who Even Came Up With The Idea?

First one I ever saw was a bulletin board type, used by the NASA bigwigs. First one I ever used was AOL, in the early-mid 90s.

The idea of a chat room has been around since time began talking around a camp fire,meeting at the local burger joint/soda shop,yacking down at the corner store,sitting on the front porch,tv talk shows,e- mails,pen pals,party phone lines...even sites that are not chatrooms become places to yack back and forth....all someone did was define it as a chatroom, make a word up for it....now you have blogs and facebook old ideas remade to work on the internet...so I would say no one person/group can claim rights to the idea of a chat room...just my opinion
