The development of advertising

In the beginning of advertising during the Industrial Revolution, it was mainly used to promote novelties and fringe products.
Then there were a lot of new companies and so brand-naming became necessary.

The economic depression, which lasted from 1873 to 1894, brought on a crisis of over-production and under-consumption.
The smaller businesses realized that they would be in a better situation if they combined with other small businesses.

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.
Advertising of this period had reached the "stage of persuasion as distinct from proclamation or iteration", 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.
