Which era is characterized by the growth of mass media alongside industrialization?

The correct answer is the Seedbed Era, which is characterized by the growth of mass media that paralleled industrialization. This era, which roughly spanned from the late 19th century into the early 20th century, was fundamentally transformative as it marked the emergence of modern communication techniques and the proliferation of media channels such as newspapers, magazines, and later radio.

During this period, the development of these mass media channels significantly influenced public relations practices. As industries grew and the economy expanded, businesses realized the importance of communicating effectively with the audience. Public relations began to take shape as a profession, aimed at managing the flow of information and shaping public perception. The methods used during this time, including press releases and public events, laid the groundwork for contemporary public relations strategies.

The other options, while notable periods in history, do not represent the same synergy between mass media growth and industrialization.
