Remember classified ads? They were in newspapers. The best classified ad was the one that said "SEND $1 FOR INFORMATION." That guy made a lot of money from that ad. I don't even know if he sent out any information -- I bet he didn't. But that was before the internet. He probably couldn't get away with that sort of thing now because there are no more newspapers.
