# History of Radio and Broadcasting Credit: SteTy — published free in the Skills Hub Radio went from Morse-code sparks to the first true mass medium in a single generation, then survived television by reinventing itself around talk, music formats, and eventually the podcast. This skill traces that arc — Marconi to Serial — and extracts the live-talk craft each era invented, so you can recognize (and use) the techniques baked into every modern audio format. ## Overview Broadcasting's history is a sequence of constraints turning into crafts. Spark-gap transmitters could only send dots and dashes, so operators developed brevity codes. Early microphones and live-only technology forced performers to create worlds with voice and sound effects alone. Television stole radio's scripted programming in the 1950s, so radio survived by becoming local, musical, and conversational. Podcasting removed the schedule and the license, and the craft pivoted again — toward intimacy and on-demand niche depth. Each transition kept the core skill: one voice, holding unseen listeners, in real time. ## Core Principles - **The medium rewards the voice, not the script.** Radio's stars were always people who sounded like someone, not everyone. - **Liveness is the product.** Election returns, ball games, and breaking news built the audience habit; everything else filled the hours between live moments. - **Formats are survival adaptations.** Top 40, talk, and all-news were not artistic movements first — they were answers to television. - **Intimacy scales.** A broadcast voice speaks to thousands but is heard by one person at a time. Every era's winners understood this. - **Regulation shapes content.** Licensing, the Radio Act of 1927, and the FCC (1934) decided who could speak and roughly what they owed the public. ## Techniques - **Signposting for the ear:** Golden Age hosts constantly re-oriented late tuners-in — recapping who is speaking, where the scene is, what just happened. Audio-only audiences cannot rewind. - **The theatre of the mind:** Radio drama (e.g., *The Shadow*, debut 1930 as narrator, 1937 as lead; *The Lone Ranger*, WXYZ Detroit, 1933) built sets from sound effects — a cellophane wrapper near the mic became fire; coconut shells became horses. - **Appointment structure:** Networks NBC (1926, Red and Blue networks), CBS (1927), Mutual (1934), ABC (1943, from NBC Blue) trained audiences to return at fixed times, the ancestor of every release schedule today. - **The Murrow standard:** Edward R. Murrow's WWII rooftop reports from London (1940 Blitz) set the template for broadcast news presence — calm, specific, on-scene. - **Format clock discipline:** Todd Storz and Gordon McLendon invented Top 40 in the early 1950s (repeating a small playlist like a jukebox), teaching radio to be a loop listeners join mid-stream rather than a program they follow. - **Caller as co-host:** Talk radio, supercharged after the FCC repealed the Fairness Doctrine in 1987 and Rush Limbaugh went into national syndication in 1988, turned audience phone calls into free, unpredictable content. ## Worked Examples - **December 24, 1906:** Reginald Fessenden transmits voice and music from Brant Rock, Massachusetts — ship operators expecting Morse hear a man reading scripture and playing violin. The leap from telegraphy to broadcasting in one night. - **November 2, 1920:** Westinghouse's KDKA, Pittsburgh, broadcasts Harding–Cox presidential election returns — the conventional birthday of commercial radio. By 1940, 83% of U.S. homes owned a set. - **October 30, 1938:** Orson Welles and the Mercury Theatre air *The War of the Worlds* on CBS as fake news bulletins. Some late tuners believed it; newspapers — radio's rivals for ad money — inflated the panic story. Lesson: format realism is a loaded weapon. - **1933:** Edwin Armstrong patents wide-band FM; commercial FM follows in the 1940s but only wins in the 1960s–70s when music listeners demand fidelity AM can't deliver. - **2004–2014:** Ben Hammersley coins "podcasting" in *The Guardian* (Feb 2004); Adam Curry's iPodder and *Daily Source Code* prove RSS-to-iPod audio; Apple adds podcasts to iTunes (June 2005, correcting earlier misprints of 2015); *Serial* (2014) makes on-demand audio a mainstream habit. ## Common Pitfalls - **Crediting Marconi with "radio" alone.** Hertz proved the waves (1887), Fessenden sent voice, Lee de Forest's audion tube (1907) made amplification practical. Broadcasting is a relay race. - **Repeating the War of the Worlds panic as fact.** The scale of panic is genuinely disputed; the well-documented panic is partly a print-industry counterattack. - **Assuming TV "killed" radio.** TV killed radio's *programming model* — its drama, comedy, and variety moved to television — but total listening grew through car radios, transistors (Regency TR-1, 1954), and FM. - **Treating podcasting as "radio on the internet."** Its break with radio is structural: no license, no schedule, no geography, and metrics per-episode rather than per-quarter-hour. ## Practice Drills - Listen to one Golden Age episode (*Suspense* or *The Shadow*) with a notebook; log every signpost that tells a late joiner where they are. - Read a news script aloud while a timer runs; practice Murrow pacing — short sentences, concrete nouns, no adjectives you can't picture. - Take any 10-minute talk segment and mark where a caller/host resets the topic for new listeners. Count the resets; that's the format clock working. - Record a 3-minute segment twice: once as a 1920s announcer, once as a podcast host. Note what changes — distance, formality, assumed audience size. ## When to Use and Limits - **Use it when:** a task calls for history of radio and broadcasting, as laid out in the Techniques and Worked Examples above. - **Watch first for:** Crediting Marconi with "radio" alone.; Repeating the War of the Worlds panic as fact.; Assuming TV "killed" radio. (see Common Pitfalls). - **Limits:** this is a general reference drawn from public sources; it is a starting point for practice, not a full course, and attributions and dates should be checked against the cited sources before quoting them. ## Quick Reference - 1887 Hertz detects radio waves · 1895 Marconi wireless telegraphy · 1906 Fessenden voice broadcast; de Forest audion · 1920 KDKA · 1926 NBC · 1927 Radio Act / FRC; CBS · 1934 FCC · 1938 War of the Worlds · 1940 Murrow's London · 1950s Top 40 + transistor · 1987 Fairness Doctrine repealed · 1988 Limbaugh syndicated · 2004 "podcasting" coined; iPodder · 2005 iTunes podcasts · 2014 Serial. --- *Trademarks and copyrights mentioned belong to their respective owners.
