Final answer:
The newspapers' sale of extra copies is associated with "yellow journalism," a term denoting the practice of sensationalizing news to boost sales. Historical figures like Joseph Pulitzer used such tactics, and investigative muckrakers contributed to this tradition by exposing scandals, thereby increasing circulation.
Step-by-step explanation:
The statement "The newspapers sold extra copies with the story of the verdict" broadly relates to the historical concept of yellow journalism, where newspapers would sensationalize stories to boost sales and circulation. Newspapers printing scandalous front-page news and inflammatory details, can be traced back to the late 19th and early 20th centuries with the rise of the cheap press and increased buying power among the general populace. This era saw publishers like Joseph Pulitzer using tactics such as sensational headlines to sell papers, a trend that continued in different forms even through the 20th century.
Muckrakers also contributed to the shaping of this journalistic environment, producing in-depth investigative journalism that often exposed corruption or scandal, further fueling the sale of newspapers. Whether through investigative commentaries or sensational stories, newspapers tapped into the public's desire for entertaining and sometimes scandalous reading material, resulting in the sale of extra copies.
