History of Television: Baird to Streaming Disruption

A Ventriloquist's Dummy Became the First Television Image

On January 26, 1926, John Logie Baird demonstrated moving television images to approximately 50 scientists at the Royal Institution of Great Britain in London. His demonstration used a ventriloquist's dummy named "Stooky Bill" as the subject — the dummy's high-contrast face photographed better under Baird's crude light scanning system than human skin. The system used a Nipkow disk, a spinning cardboard disc with spiral holes that mechanically scanned light across an image at 12.5 frames per second and 30 lines of resolution. The result was a recognizable moving image, blurry and flickering, produced by a device built from a tea chest, bicycle lamp lenses, a hatbox, knitting needles, and sealing wax. Television had arrived — and it looked terrible.

Mechanical vs. Electronic: The Founding Rivalry

Baird's mechanical system had a fundamental ceiling. Increasing resolution required spinning the Nipkow disk faster — a mechanical constraint that limited image quality regardless of how much the electronics improved. The solution required replacing moving parts with electrons.

Philo Taylor Farnsworth, a 21-year-old inventor from Rigby, Idaho, filed a patent for an all-electronic television system on January 7, 1927, describing a system that scanned images using a beam of electrons — what he called an "image dissector." On September 7, 1927, Farnsworth's system successfully transmitted a moving image of a straight line — chosen because it was the simplest possible shape to verify accurate transmission — in his San Francisco laboratory. When his financial backer asked if there was any money in the new invention, Farnsworth reportedly transmitted an image of a dollar sign in response.

• RCA and its chairman David Sarnoff attempted to acquire Farnsworth's patents, offering him a position as an employee rather than a licensing deal. Farnsworth refused.
• The patent dispute between Farnsworth and RCA ran for seven years. In 1934, the U.S. Patent Office ruled in Farnsworth's favor on all counts, finding that his 1927 patent predated RCA engineer Vladimir Zworykin's competing claims.
• RCA ultimately paid Farnsworth licensing fees beginning in 1939 — the first time RCA had ever paid royalties rather than collected them — a reversal that Sarnoff reportedly never forgave.

Early Broadcasting: NBC, CBS, and Television Standards

Commercial television broadcasting began in earnest after World War II. The National Broadcasting Company (NBC) and Columbia Broadcasting System (CBS) both launched regular programming in 1941 in New York, but wartime restrictions halted civilian manufacturing and limited expansion. Broadcasting resumed and expanded rapidly after 1945.

The Color War: NBC vs. CBS

The transition to color television was not a technical story — it was a corporate one. CBS developed a color system based on a rotating color wheel that produced excellent image quality but was mechanically incompatible with existing black-and-white receivers. NBC's system, developed by RCA, used electronic color encoding compatible with existing receivers: a black-and-white television could receive a color broadcast in monochrome. The FCC approved the CBS system in 1950. RCA immediately challenged the ruling in court, and the Korean War provided a justification for suspending color broadcasting for national industrial reasons. By the time the FCC reconsidered in 1953, RCA's compatible system had improved sufficiently to win approval.

The NTSC (National Television System Committee) color standard adopted in 1954 encoded color as two chrominance signals superimposed on the existing 525-line luminance signal, allowing backward compatibility with the 40 million black-and-white sets already in American homes. NBC, owned by RCA, broadcast its first coast-to-coast color program on January 1, 1954. RCA sold its first consumer color television set, the CT-100, that same year for $1,000 — equivalent to approximately $11,000 in 2024 dollars.

Cable, Satellite, and HDTV

Over-the-air broadcasting's dominance eroded through the 1970s and 1980s as cable television expanded beyond its original purpose of delivering broadcast signals to rural areas. HBO launched as the first pay cable channel on November 8, 1972, showing a hockey game from Madison Square Garden to 365 subscribers in Wilkes-Barre, Pennsylvania. CNN launched in 1980 as the first 24-hour news network, demonstrating that cable channels could build audiences through specialized rather than broad-appeal content.

• Direct broadcast satellite (DBS) services DirecTV and EchoStar (DISH Network) launched in 1994, offering 150+ channels to consumers with 18-inch dishes — a direct competitor to cable without requiring cable infrastructure.
• The Advanced Television Systems Committee (ATSC) standard for digital high-definition television was approved in 1996. The U.S. completed its transition from analog to digital broadcasting on June 12, 2009, when all full-power television stations switched off their analog transmitters.
• HDTV at 1080i (1080 lines, interlaced) and 720p (720 lines, progressive) offered approximately six times the resolution of the NTSC standard — a perceptual improvement analogous to moving from a photocopy to an original document.

Streaming Disruption

Netflix launched its streaming service in 2007, initially as a supplement to its DVD-by-mail business. By 2013 it was producing original content; House of Cards became the first streaming-original series to win a Primetime Emmy. By 2023, Netflix had 260 million subscribers across 190 countries — more than any single broadcast network in history. Linear television viewership in the United States fell below streaming viewership for the first time in July 2022, according to Nielsen data, marking a structural shift rather than a trend. The medium Baird demonstrated with a ventriloquist's dummy had fragmented across a thousand services, delivered over networks that Baird could not have imagined, to devices he never conceived.
