History of Media, Writing, Broadcasting, and Computing

Vocabulary flashcards covering the material history, theory, and technological transitions of writing, mechanical print, visual media, broadcasting, and computing.

Speech (Operational Definition)

Thought packaged into sound, where the physical medium material is vibrating sound waves traveling through air and the medium content is the encoded mental representation.

Principle of Linearity in Acoustic Speech

The structural constraint wherein human vocal anatomy prevents the simultaneous production of discrete phonetic sounds, forcing speech to unfold as a sequential chain of phonemes along an axis of time.

Papyrus Scroll

A fragile, single-sided, continuous writing surface developed in Egypt circa $3000\,\text{BCE}$ from reed piths, structurally binding reading to linear unrolling and oral recitation.

Parchment Codex

A bound leaf book format fabricated from scraped, stretched animal hides that decoupled reading from acoustic linearity to enable non-sequential browsing and tabular cross-referencing.

The $1436\,\text{CE}$ synthesis by Johannes Gutenberg in Mainz, Germany, combining reusable mold-cast alloy movable metal type, oil-based ink, and an adapted wooden screw press.

Imagined Community

Benedict Anderson's definition of a nation as a socially constructed, modern political community that is inherently limited in territorial boundaries and conceived as sovereign.

Homogeneous, Empty Time

The modern secular temporal consciousness marked by 'meanwhile,' where simultaneous events across geographic space are linked by clocks and calendars rather than messianic or cosmological time.

Optical Semaphore Telegraphy

An $18\text{th}$-century French long-distance visual communication system utilizing hilltop relay towers fitted with rotating mechanical shutters observed through telescopes.

Electric Morse Telegraphy

A point-to-point transmission apparatus invented by Samuel Morse in $1837\,\text{CE}$ that converted messages into binary on/off electrical impulses transmitted along wires.

Mesopotamian Cylinder Seals

Miniature engraved stone cylinders dating to circa $3100\,\text{BCE}$ rolled across wet clay to imprint continuous, verifiable pictorial signatures and administrative seals.

Intaglio

A graphic printmaking method where lines are incised into copper or zinc plates with a burin or etched with acid, leaving ink in recessed grooves to be transferred onto damp paper under rolling pressure.

Lithography

A chemical printing process invented in $1796\,\text{CE}$ based on the mutual repulsion of oil and water, executed using greasy crayon on polished Bavarian limestone.

Camera Obscura

An optical phenomenon and apparatus where light passing through a small aperture into a darkened box or room casts an inverted, reversed image of the external scene onto an opposite wall.

Heliography

The photographic process developed by Nicéphore Niépce using a photosensitive Bitumen of Judea coating on a $16 \times 20\,\text{cm}$ pewter plate that hardened upon sunlight exposure.

Daguerreotype

An $1839\,\text{CE}$ photographic process that exposed iodine-sensitized, silver-plated copper sheets in a camera obscura, developing the latent image over heated mercury vapor ($60^\circ\,\text{C}$).

Gelatin Silver Mechanism

A photographic process where microscopic silver halide crystals suspended in a gelatin colloidal emulsion are exposed to photons, forming metallic silver specks amplified in developer baths.

Phenakistiscope

An $1830\text{s}$ optical device created by Joseph Plateau using a spinning cardboard disc with perimeter vertical slits, creating the illusion of continuous motion via persistence of vision.

Phantasmagoria

An $1800\text{s}$ theatrical presentation using rear-projection magic lanterns mounted on concealed tracks behind gauze screens to project moving illusions of ghosts, skeletons, and apparitions.

Aura (Walter Benjamin)

The unique presence of an original artwork in time and space, encompassing its physical history, spatial location, and material authenticity, which decays during mass mechanical reproduction.

Cult Value versus Exhibition Value

Walter Benjamin's formulation of the historical shift wherein art departs from its traditional grounding in sacred ritual and religious cult to serve public, secular exhibition and mass politics.

Broadcasting

The electronic transmission of audio or video content to a dispersed public in an open, one-to-many topology, typically utilizing radio frequency bands of the electromagnetic spectrum.

Bandwidth

The physical spectral width measured in Hertz ($\text{Hz}$) that a given signal occupies within the electromagnetic frequency continuum.

Radio Telephony

The wireless transmission of voice and acoustic sounds, first achieved by Reginald Aubrey Fessenden on Christmas Eve in $1906\,\text{CE}$.

Radio Act of 1912

Regulatory legislation enacted after the sinking of the RMS Titanic that mandated $24\text{-hour}$ shipboard radio watchkeeping, standardized distress frequencies, and instituted federal airwave licensing.

Aird Commission

A Canadian royal commission established in $1928\,\text{CE}$ that investigated American radio dominance and recommended the formation of a publicly owned national broadcasting system.

Amplitude Modulation (AM)

A transmission method where the amplitude of a carrier wave varies proportionally with the incoming audio signal while frequency stays constant, occupying a narrow bandwidth ($\approx 10\,\text{kHz}$).

Frequency Modulation (FM)

A transmission method where the carrier wave frequency fluctuates to encode audio while amplitude remains uniform, providing high fidelity and noise resistance across a wide bandwidth ($\approx 200\,\text{kHz}$).

Affect (Affect Theory)

A non-conscious, pre-linguistic bodily experience of intensity and visceral feeling operating on human senses prior to conscious cognitive processing or structured emotion.

Narrowcasting

The structural reorganization during the $1950\text{s}$ where radio adjusted to the rise of television by programming for niche sub-audiences and localized formats like music, talk, and news.

Jacquard Loom

An automated textile loom invented in $1804\,\text{CE}$ controlled by sequences of punched pasteboard cards, establishing that physical punched holes could direct automated machine behavior.

Analytical Engine

Charles Babbage's conceptual general-purpose programmable digital computer designed with a mechanical processing core ('The Mill'), memory ('The Store'), and punch-card inputs.

Hollerith Punch Card Tabulator

An electromechanical apparatus developed by Herman Hollerith to process the $1890\,\text{CE}$ US Census, using spring-loaded pins that completed electrical circuits through punched card holes into mercury wells.

Memex

A theoretical desktop microfiche and optical device conceptualized by Vannevar Bush in $1945\,\text{CE}$ designed to link and retrieve personalized associative trails of information, anticipating hypertext.

ARPANET

The first operational decentralized packet-switching network launched in $1969\,\text{CE}$, originally connecting four nodes: UCLA, Stanford, UC Santa Barbara, and the University of Utah.

Web 2.0

The interactive read-write evolution of the World Wide Web emerging after $2005\,\text{CE}$, defined by dynamic user-generated content, social networks, and algorithmic advertising.

Media Convergence

The technical consolidation of previously discrete media devices and capabilities—such as still photography, telephony, computing, and audio playback—into a single integrated hardware device.

Remediation

The process whereby newer digital media forms absorb, refashion, and borrow the conventions, structures, and aesthetics of pre-existing older media technologies.

Surveillance Capitalism

An economic paradigm defined by Shoshana Zuboff where digital platforms harvest private human behavioral data as raw material to predict, influence, and modify future user actions for profit.
