During the early stages of the Industrial Revolution, advertising was a relatively straightforward means of announcement and communication and was used mainly to promote novelties and fringe products. But when factory production got into full swing and new products, e. g. processed foods, came onto the market, national advertising campaigns and brandnaming of products became necessary. Before large-scale factory production, the typical manufacturing unit had been small and adaptable and the task of distributing and selling goods had largely been undertaken by wholesalers. The small non-specialized factory which did not rely on massive investment in machinery had been flexible enough to adapt its production according to changes in public demands. 　　But the economic depression which lasted from 1873 to 1894 marked a turning point between the old method of industrial organization and distribution and the new. From the beginning of the nineteenth century until the 1870s, production had steadily expanded and there had been a corresponding growth in retail outlets. But the depression brought on a crisis of over-production and under-consumption ― manufactured goods piled up unsold and prices and profits fell. Towards the end of the century many of the small industrial firms realized that they would be in a better position to weather economic depressions and slumps if they combined with other small businesses and widened the range of goods they produced so that all their eggs were not in one basket. They also realized that they would have to take steps to ensure that once their goods had been produced there was a market for them. This period ushered in the first phase of what economists now call "monopoly capitalism", which, roughly speaking, refers to the control of the market by a small number of giant, conglomerate enterprises. Whereas previously competitive trading had been conducted by small rival firms, after the depression the larger manufacturing units and combines relied more and more on mass advertising to promote their new range of products. 　　A good example of the changes that occurred in manufacture and distribution at the turn of the century can be found in the soap trade. From about the 1850s the market had been flooded with anonymous bars of soap, produced by hundreds of small manufacturers and distributed by wholesalers and door-to-door sellers. Competition grew steadily throughout the latter half of the century and eventually the leading companies embarked on more aggressive selling methods in order to take customers away from their rivals. For instance, the future Lord Leverhulme decided to "brand" his soap by selling it in distinctive packages in order to facilitate recognition and encourage customer loyalty. 　　Lord Leverhulme was one of the first industrialists to realize that advertisements should contain "logical and considered" arguments as well as eye-catching and witty slogans. Many advertisers followed his lead and started to include "reason-why" copy in their ads. For example, one contemporary Pears soap ad went into great detail about how the product could enhance marital bliss by cutting down the time the wife had to spend with her arms in a bowl of frothy suds. And an ad for Cadbury’’s cocoa not only proclaimed its purity but also detailed other benefits. "for the infant it is a delight and a supports for the young girl, a source of healthy vigour; for the young Miss in her teens a valuable aid to development..." and so on. As the writer E. S. Turner rightly points out, the advertising of this period had reached the "stage of persuasion as distinct from proclamation". Indeed advertise or bust seemed to be the rule of the day as bigger and more expensive campaigns were mounted and smaller firms who did not, or could not, advertise, were squeezed or bought out by the larger companies. One of the more aggressive selling methods in the soap trade by the leading companies was to
