Folklorist Richard M. Dorson also cites the "booster impulse, mingled with entrepreneurial hoaxing" as the way that Douglas with its jackalope, Churubusco with its giant turtle, and other towns with their own local legends rise above anonymity. He traces the impulse and the methods to the promotional literature of colonial times that depicted North America as an earthly paradise. Much later, in the 19th century, settlers transferred that optimistic vision to the American West, where it culminated in "boosterism". Although other capitalist countries advertise their products, Dorson says, "...the intensity of the American ethos in advertising, huckstering, attention-getting, media-manipulating to sell a product, a personality, a town is beyond compare."
