"I think so. D'you think it will work?" "If there is a primitive culture of the most low-grade organization there, there will also be one or more leading characters. A man of fame or power--or infame and power--whose person will be in the active minds of a large number of hypothetical inhabitants. We should be able to get some sort of response even if the whole thing is primitive as all get-out. But let's take a look before we do anything that's likely to get us into trouble. We're late now, another few hours isn't going to hurt much more." The discussion in the dome on Mercury's dark side abated as the trio went to work. Scyth began to tinker with his menslators; Chat began to prowl the confines like a caged animal, thinking deeply, and Bren Hallow went back to his massive equipment that was designed to create a galactic beacon. * * * * * On this Third Planet of Sol there were still captains and kings and presidents and commissars and a couple of dictators and a new invention or two, all of which professed to be gentle guardians of the public rights. Only the names had changed, some in violence and some in peace. The names of places were about the same; a few had disappeared in the heat of ideology, but by and large things and people persisted despite atoms, politics and the cussedness of human nature. Youth was still going to hell--and old age was still fuddy-duddy. One apparent change might have been noticed by a man of the middle of the century, and even he would have expected it. The history of this change reads like this: A few years after Global War I, the manufacturer of a breakfast food product known as "Oatflakes" realized a rather monumental increase in the sale of his product. Conscientious investigation showed that this increase was not due to the public becoming addicted to oatmeal as a morning, noon and night diet (with a midnight snack tossed in) but entirely due to a new plaything called the "Wireless." Wireless, it was found, required as a major component about a quarter of a mile of wire wound around the cylindrical box in which the oatflakes were packed. Some years later, when the first home-manufacture of radio sets slowed because of professional manufacture of commercial radio, the sale of Oatflakes dropped to normal. At this point the manufacturer of the food product realized that the pathway to high sales was not along the contents, but along the package. Let the public buy the stuff for the box, or the box-top. If he wants to eat the stuff on the inside, that's his business! So in the early-middle years of the century there arose a character called Hopalong Cassidy, who portrayed an Old West chivalry and heroic strength great enough to sell boxtops by the gross ton. He tied-in sales with toy and clothing makers until business reached the Law of Diminishing Returns. After selling spurs for roller skates the brains ran out of ideas and turned to new fields.
