Soap companies sought to compete with each other through advertising and the advertising industry probably owes a great deal to the soap companies for its growth.
Originally magazines advertised soap, and it was common to find lengthy advertisements describing soap manufacturer's products in great detail.
This was before the advertising industry discovered it could market a product without any mention of the product's merits!
Soon radio became the main promoter of the soap companies, sponsoring what are now known as soap operas.
While many people think of soap operas as TV programs, they were originally radio shows.
How many people would think while watching a soap opera on television, that we have the soap manufacturing companies to thank for that definition?
