Radio Lecture

The progression of screen mass media is not linear due to overlaps, such as skipping over significant sections like radio.

Wireless Telegraphy: The practice of transmitting sound wirelessly began with wireless telegraphs, which predated radio.
- First text message sent using radio waves occurred in the early 1900s.
First Radio Broadcast: The first radio broadcast took place in 1920 by the Westinghouse Corporation.
- It consisted solely of music and marked the beginning of regular radio programming.

KDKA: One of the first radio stations to broadcast regularly.
- Launched in 1920, it reported the presidential election results, signifying its importance in radio history.
Early Advertisers and Sponsors: Many companies, including newspapers, banks, and local businesses, established their own radio stations.
- Notable example: Dr. John Romulus lecturing on station KFKB in Kansas.

By the mid-1920s, radio became a ubiquitous piece of furniture in American living rooms, essential for family entertainment and constant communication.
AM versus FM: During this time, only AM radio was available.
- FM radio technology was developed later to address AM's limitations, such as static and a narrow sound range.

Howard Armstrong's Contribution: An engineer who developed frequency modulation (FM), which eliminated static compared to AM.
- FM enabled a wider band of sound and clearer reception.
- Despite its advantages, FM faced resistance from established AM broadcasters and was not widely adopted immediately.

David Sarnoff of RCA played a pivotal role in the establishment of the National Broadcasting Company (NBC) in 1926.
- Established the first radio network linking 50 stations across 24 states to unify broadcasts.
Early radio history was marked by fierce rivalry, especially between Sarnoff and Armstrong, representing different broadcasting technologies.

Radio became a trusted source of news and entertainment, replacing live music and social gatherings.
By the mid-1930s, families would gather around radio dramas, which could evoke strong emotional responses and build community trust.

Orson Welles' 1938 Broadcast: A scripted radio drama that inadvertently caused mass panic due to its realistic portrayal of a Martian invasion.
- Broadcasted on Halloween, many listeners mistook it for a real news report, leading to a call for FCC regulation of radio content.
- Resulted in increased awareness of the potential impact of radio on public perception and the necessity for regulation.

In response to the panic induced by the War of the Worlds broadcast, the Federal Radio Commission was established in 1927, later renamed FCC in 1934.
The FCC aimed to prevent monopolistic practices in broadcasting, highlighting the conflict between NBC and new radio stations.

The emotional connection built between FDR and listeners exemplified radio's power as a mass communication tool.

The historical development of radio reflects a transition in communication, entertainment, and public information dissemination.
Key figures, technological advancements, and regulatory frameworks shaped the evolution of radio as a vital aspect of American culture and society.
