When someone decides to change a source with invalid, incorrect, irrelevant, or just idiotic information.
Answer: Catalogs
Explanation:
In 1872, Aaron Montgomery Ward took advantage of the growing shipping business in America to establish the Montgomery Ward Company.
The company's modus operandi was to showcase goods in a catalog and distribute it to people who would then order the products they liked. The company would then deliver it by rail.
Starting with a single-sheet catalog that offered only 163 items, the company grew to serve 3 million customers by the year 1904 and are still in existence today.
