There were a decent number of couples who met online, before meeting online meant a dating site. There were BBSes, Usenet, and some early discussions sites. I'm sure people could compile a surprisingly large list of ways people met. A few years later, I even met my wife on LiveJournal, before that went weird(er). So while someone certainly could do a documentary on such things, I don't think any specific couple from that era should be holding their breath for it.
