Well I didn't start with zero, but when I turned on our first rack of recorded phone sex tape loop machines back in 1984, the day our first ad hit the newstands in LA, those fuckers all lit up like a christmas tree and never stopped playing.
I don't remember the exact timing but after a couple hours watching them clicking on continuously, my partner and I knew we'd just hit an oil gusher investment and went out for some beers to celebrate.
