The document provides a history of broadcast media from the late 19th century to present day. It discusses the key inventors and innovations in radio and television technology. Some of the major developments include Marconi sending the first radio signal across the Atlantic in 1901, Fessenden transmitting voice over radio waves in 1906, the establishment of the first radio networks in the 1920s, and the growth of cable and satellite television competing with broadcast TV in later decades. Regulations and acts like the Radio Act of 1927 and Telecommunications Act of 1996 shaped the industry as new technologies emerged.
Radio broadcasting debuted in the early 20th century and grew rapidly through the 1930s-1950s, becoming a major source of entertainment and news. Technological advances in the late 19th century led to the development of radio. Guglielmo Marconi transmitted the first radio signal across the Atlantic in 1901. The first radio voice broadcast occurred in 1906. By the 1920s-1930s, radio stations proliferated and radio ownership expanded greatly. Networks emerged providing programming. Radio faced competition from television in the 1950s, but adapted through portable radios, new formats like top 40, and focusing on news and information.
The document traces the development of television from its early experiments in the 1920s to modern technologies. Some key developments include:
- Philo Farnsworth's early experiments with electronic television in the 1920s. Regular broadcasts began in the 1930s by the BBC.
- Introduction of coaxial cable in 1936 which improved signal transmission. Color television was also developed in the 1940s-1950s.
- The 1950s saw the development of remote controls and the first satellite TV broadcasts. By the 1960s, most TVs were in color.

John Logie Baird invented the first television system in 1926. Televisions evolved from large cathode ray tube models to include rear projection, plasma, LCD, and LED screens of increasing size. Color transmission was introduced in 1954 and 3D televisions became available in 2010. Televisions have had a major social and cultural impact through entertainment and influencing public opinions while also creating environmental concerns over electronic waste disposal.
Radio developed from earlier inventions like the telegraph and telephone using electromagnetic waves to transmit audio such as music and speech without wires. Key developments included Maxwell and Hertz's work establishing the existence of radio waves in the 1860s-1880s, Marconi's successful transatlantic radio transmission in 1901, and Armstrong's invention of FM radio in 1933 which improved audio quality. Radio broadcasting began in the early 1920s and grew rapidly that decade as more people purchased receivers. However, the lack of regulation led to interference issues until the Federal Radio Commission was established in 1926 to bring order. Radio has since been used for various purposes like education, news, entertainment and more, becoming an important mass medium.
Television evolved from early experiments in the 1920s to becoming a widespread mass medium by the 1950s. Key developments included the invention of the electric television tube in the 1920s, early broadcasts in the UK and US in the 1930s, the development of television networks in the late 1940s allowing national broadcasts, and a drop in prices making TVs affordable to most Americans by the 1950s. In India, television was introduced in 1959 in Delhi and expanded slowly over the following decades, with the launch of Doordarshan and expanding coverage through terrestrial transmitters and satellites. Color transmission and commercial broadcasts were introduced in the 1970s-80s, expanding content and viewership.

Radio is the most widely consumed mass media in America, with 93% of Americans tuning in each week via AM/FM radio. There are over 12,000 radio stations broadcasting in the US, reaching 228.5 million consumers weekly. While television and digital media have grown, radio remains popular due to its portability, ability to be consumed alongside other activities, universal availability, and ability for listeners to select their preferred format.
Television originated from experiments in the late 19th century to transmit moving images through electric signals or radio waves. Paul Nipkow developed the first electromechanical television system in 1884 using a rotating disk. John Logie Baird demonstrated the first live moving images transmitted by television in 1925. Vladimir Zworykin invented the cathode ray tube in 1929, allowing the first fully electronic television system. Color television was demonstrated by Peter Goldmark in 1940 using a spinning color wheel and became more widely used after all-electronic color sets were introduced in the 1950s.
This chapter discusses the evolution of radio broadcasting from its invention in the late 19th century through Marconi's popularization of wireless technology in the early 20th century.

It also discusses the establishment of regulations and organizations like the Federal Radio Commission and FCC to oversee radio licensing and usage in the early 20th century. By the 1940s, most families owned a radio and listened for several hours daily, though the rise of affordable television began radio's decline into a mostly music-based format.
The radio was invented in the 1890s by Guglielmo Marconi. The BBC was formed in 1922 and originally had a monopoly over radio broadcasting in the UK. Over time, competition emerged from television, deregulation allowed commercial radio stations, and the internet has further expanded access to radio. Today there are over 800 radio stations in the UK, including the BBC's 10 national stations, regional stations, and local stations as well as numerous commercial options.

History: Inventors
• Early inventors and inventions paved the
way for the electronic mass media
• James Maxwell and Heinrich Hertz
demonstrated the existence of
electromagnetic radiation
3. 3
History: Inventors
WIRELESS BREAKTHROUGH:
Guglielmo Marconi
- used the results discoveries by Morse, Hertz and
Bell to expand his idea that messages should be
able to travel across space without a wire.
- he could ring a bell across the room or
downstairs without using a wire and able to
broadcast over a distance of nine miles.
4. 4
History: Inventors
- ship-to-ship, ship-to-shore communication
- dots and dashes (Morse code) aka
telegraphy
- two experimenters, Reginald Aubrey
Fessenden and Lee de Forest, advanced
Marconi’s discovery to create today’s radio
- Eventually he developed a powerful
wireless business history.
5. 5
History: Inventors
EXPERIMENTAL BROADCASTS:
Reginald Aubrey Fessenden
- began wireless experiments in United States in 1900
when he set up his National Electric Signaling
Company to attempt sending voices by radio waves.
- his 1906 experiment is considered the world’s first
voice and music broadcast.
- Violin music – Bible reading – New Year’s wish –
signed off
6. 6
History: Inventors
DETECTING RADIO WAVES:
Lee de Forest
- he called himself ‘the father of radio’ because in 1907 he
perfected a glass bulb called ‘Audion’ that could detect
waves (plus weak waves)
- Before ‘Audion’, crystal set is used to transmit signals –
can detect only strong radio waves
- ‘Audion’ became the foundation of modern radio
broadcasting.
