How did the vast continental scale of the American economy in the late 19th century shape American transportation and marketing?
The vast scale of the economy meant that it was important to have a vast transportation network and marketing procedures that could reach a wide market. Both of these things were present in the late 1800s. For transportation, we can see the development of the transcontinental railroads. For marketing, we can see that the late 1800s brought us mail order houses that were able to get catalogs to far-flung areas. Because of the railroads and the mail order companies, people anywhere in the country could buy all sorts of items and get them shipped to their homes. In these ways, the vast scale of the economy shaped transportation and marketing processes.
