Lecture Notes: History of Communication Technologies and Information Access

Setting the stage: why study communication across time?

• Ashley’s backstage anecdote sets up the core question: how have humans communicated across distance, from ancient times to the present? The speaker imagines Alexander the Great as a time traveler and ponders how Stephen Colbert’s era of fast communication would change things.
• Central idea: speed of communication has altered enormously over history; we’ll trace the broad arc from writing and messengers to digital networks and AI.
• The lecture emphasizes two guiding touchstones for this course:
  • Technology: how humans change their environment to make life easier; for example, writing is a technology, and money is a technology (representative exchange).
  • Religion: nearly all cultures studied have religion; religious ideas and institutions are deeply intertwined with information, power, and governance.
• Key terms introduced early:
  • Writing as a technology of representation: “representative reality.”
  • Money as a technology of representation: “representative exchange.”
  • The balance between literacy, written texts, and visual/iconographic communication (iconography) when reading rates are low.
• Core thesis to keep in mind: access to information and the speed of its dissemination shape power, culture, and everyday life.

Writing and early media: materials, languages, and basic assumptions

• Writing materials across cultures:
  • Silk in the Han dynasty (writing on silk as a paper analogue).
  • Amarna letters from the New Kingdom (Egypt) as early examples of political correspondence.
  • A letter from King Henry VIII of England (late medieval/early modern Europe).
  • Handwritten communications like basic addresses and signatures.
• Core assumption behind any writing system:
  • There must be enough people who can read and write to make literacy worthwhile; otherwise, writing becomes an elite advantage or is replaced by other media (icons, memory, oral tradition).
• Language and basic literacy:
  • Writing is tied to language itself; multiple languages and scripts co-exist across civilizations, often with language barriers to access.
• Two interlinked points the course emphasizes:
  • Writing is a technology; its adoption changes how information is produced and circulated.
  • Religion intersects with communication: religious institutions often control or mediate knowledge and public messaging.
• Early non-textual forms of communication:
  • Iconography (images telling stories) becomes crucial in societies with low literacy; examples include Ashurbanipal’s lion hunting, biblical scenes in Russian Orthodox churches, and Mayan king imagery.
  • Political cartoons and other visual media illustrate ideas when literacy is limited.

From letters to public notices: public vs. private messaging

• Letters and private messages:
  • A typical letter (royal to royal, or from ruler to subject) required a writing medium and a reader who could interpret it.
• Public notices and mass messaging emerge as a response to the need to talk to larger audiences:
  • Roman acta diurna (daily public announcements).
  • Chinese tapǔ (tāi-pao) public notices posted on silk or rice paper.
  • Medieval broadsheets and the rise of newspapers.
• The necessary prerequisites for public messaging:
  • A literate audience: enough people who can read for the message to have impact.
  • Public access to writing materials and distribution networks.
• The role of “assumed readers”:
  • If literacy is scarce, societies rely on oral culture, visual storytelling, religious authorities, or magistrates to disseminate information and enforce loyalties.

Transportation and speed: the logistics of moving messages

• Why boats are the preferred transport method in many regions:
  • Boats enable efficient movement of goods and messages along rivers and seas; they avoid the logistical bottlenecks of overland fodder and heavy wagon loads.
• The later role of horses in message delivery:
  • Horses become essential for relay systems: riders horseback between stations.
  • Typical relay leg distance: ext{distance per leg} \, \approx \, 15\,\text{miles}.
  • A horse can gallop for roughly 20\text{ minutes} before needing a rest; the relay continues with a fresh horse.
  • This relay system enables rapid communication over long distances: a message from Susa to Sardis could reach its destination in about a week, a remarkable speed for the ancient world.
• The Persian postal network (royal road) and geography:
  • The network linked major centers like Susa and Sardis, with the Menander River aiding riverine transport and protecting routes.
  • The road system had policing to deter brigands and ensure faster travel.
• The broader historical parallel:
  • The Pony Express in the United States (19th century) became the modern cultural shorthand for rapid, relay-based mail across difficult terrain; the phrase “neither rain nor snow nor sleet nor the dark of night” later became associated with postal speed and reliability.
• Practical takeaway:
  • The speed of communication is bounded by transportation technology and relay logistics; improvements in transport repeatedly unlock faster dissemination of information.

Public notices, newspapers, and the rise of mass information

• Public notices across cultures:
  • Roman acta diurna; Chinese tapǔ; medieval broadsheets; newspapers emerging as a mass medium.
• The core assumption for public messaging remains literacy:
  • Readers must be able to access and interpret the content for the message to have public impact.
• The transition from individual letters to mass media marks a shift in political engagement and public discourse.

Literacy, reading, and the power of images (iconography)

• Literacy remains uneven across societies:
  • In many ancient contexts, more people could not read than could read; pictures and ritual storytelling filled the gap.
• Iconography as a storytelling technology:
  • Visuals were used to convey myths, political authority, religious narratives, and social norms when written text was inaccessible to many.
  • Examples discussed: Ashurbanipal’s lion hunt; biblical scenes in churches; Mayan king imagery; political cartoons.
• The rise of the printing press as a game changer for literacy:
  • Gutenberg’s movable type dramatically reduced the cost and time of reproducing text.
  • Ancient publishing existed (scribes copying text), but it was labor-intensive and costly; mass production was feasible only with movable type.
  • The Chinese achieved movable-type printing about five centuries earlier than Gutenberg (roughly around the 9th–11th centuries to 15th century range, depending on source), illustrating concurrent development of printing technologies.
• The broad social consequence:
  • With cheaper, faster production of texts, books become more accessible; literacy spreads; information diffuses more rapidly across societies.

Technology accelerates communication: from telegraph to television

• Telegraphs and early wire-based communications:
  • Morse code and the electric telegraph introduced near-instantaneous long-distance messaging via wired networks.
• The telephone and later communications technologies:
  • The telephone (late 19th century) enables real-time voice communication across distances.
  • Telegrams facilitated rapid message delivery, often used for important news.
  • The dial telephone era brings a tactile, direct mode of personal communication.
  • Early mobile phones and fax machines represent the push toward wireless and document transmission.
• Wireless media and mass media:
  • Radio emerges in two forms: amateur (ham) radio and commercial/broadcast radio.
  • Newsreels and early cinema deliver moving images and sound; cinema becomes a new venue for news and culture.
  • Television adds the crucial element of seeing as well as hearing, with famous anchors (e.g., Walter Cronkite) illustrating the arrival of “seeing is believing” in news.
• The modern era of AI and digital media (forward-looking note):
  • The rise of AI enables generation of “fake” people and content; authenticity and verification become critical issues.
• The Internet and early digital communications:
  • Old-school bulletin boards, Fortran-based email, Usenet forums, and the early Mosaic browser prefigure the World Wide Web; dial-up connections required long wait times and limited images.
  • The net effect: radically expanded, more interconnected audiences and faster dissemination of information—with new challenges around credibility and manipulation.
• Synthesis: each leap in technology expands reach and speed but also raises new questions about trust, literacy, and access.

Libraries, access to information, and social inequality in knowledge

• The 19th–20th century library revolution:
  • Andrew Carnegie funded 2{,}509 public libraries across the US and Canada, dramatically expanding access to information for the general public.
  • In 1975, many households still could not afford encyclopedias; those with access relied on public libraries, which were sometimes the only source of knowledge outside major urban centers.
• The limits on access in earlier times:
  • Before widespread public libraries, many people depended on a county doctor, a preacher, or a one-room schoolhouse for any reference materials.
  • Reading ability and literacy were prerequisites for meaningful access to information; knowledge was mediated by those who could read and afford books.
• The rise of public libraries and the democratization of knowledge:
  • Carnegie’s libraries are framed as a positive step toward information democratization, despite his otherwise problematic character.
• The challenge of language and access in different regions:
  • In the Middle East, the House of Wisdom in Baghdad stood out as a hub of learning with relatively open access to libraries and collections, albeit still limited by language barriers (Arabic vs Kalabi, Middle Persian).
• Distribution of knowledge and the politics of access:
  • Education and information were historically concentrated among elites; equal access is a relatively modern development in many contexts.
• The “spotlight” metaphor for history and preservation:
  • History depends on what gets written down and preserved; different civilizational “spotlights” illuminate different eras, while others fade away.
• The role of language access and multilingual knowledge:
  • Language barriers shaped what could be studied, read, and shared across cultures.
• The House of Wisdom and the Baghdad library tradition:
  • Abbasid scholars cultivated a diverse collection, with fewer restrictions on collections and translations, but language access remained a gatekeeper (Arabic or Kalabi required).

Knowledge, religion, and politics: how belief systems intersect with public life

• Religion as a public, political system:
  • Religion is not separate from public life; magistrates and public officials often performed religious duties (public sacrifice) as part of governance.
  • Taxation and death are framed as certainties in many ancient societies, and religious rituals helped manage social order around these certainties.
• The two dominant patterns of belief in the ancient world:
  • Polytheism and pantheons: multiple deities with functions (sea, war, justice, harvest, etc.).
  • The concept of atheism in the ancient world is nuanced: from the Greek term a-theism (not my gods) to actual widespread belief in multiple gods.
• Inclusive vs. exclusive religion:
  • Inclusive/religion as public practice: worship of many gods by individuals and communities; the idea that all gods might be “real” in some form.
  • Exclusive religion: the belief that one’s own god is the only true deity and that others’ gods are false or demonic; implications for social cohesion and intergroup relations.
• Syncretism and homogenization:
  • Syncretism blends attributes from different deities (e.g., Apollo’s associations with healing and disease; merging of attributes across gods).
  • Homogenization (recognizing similar gods across cultures with different names) is a way to understand cross-cultural religious parallels (e.g., rain gods, war gods, wisdom gods).
• Examples and implications:
  • Gilgamesh, Samson (Heracles in Greek tradition), and other heroic figures become cross-cultural archetypes through syncretism.
  • The idea that religion and politics inform each other is not a modern invention; ancient societies often tied religious authority to public rule and law.
• Public religiosity and political legitimacy:
  • Public rituals and sacrifices served as visible demonstrations of political order and divine favor; religious actions could motivate political decisions and vice versa.
• The modern irony: separation of church and state as a modern concept:
  • In many Western contexts, there is a belief in a separation between public life and religion, accompanied by cynicism toward publicly expressed religious rhetoric; this is not universal historically.
• The cautionary note about interpreting ancient belief:
  • Avoid assuming ancient actors were irrational or gullible; they used sophisticated forms of reasoning about gods, ritual, and state power.
• A historical counterpoint: Cureus in Athens (noted as an atheist who manipulated religion):
  • This example is invoked to illustrate how religious authority and political power intersected and could be leveraged for political ends.
• Modern verification and information fidelity:
  • The lecturer emphasizes verifying information (e.g., via Snopes) in the age of AI and deepfakes, underscoring continuity with ancient concerns about authority and truth.

From analog to digital: the contemporary landscape and future prompts

• The Internet era redefines speed, reach, and validation of information:
  • Digital networks enable instant, global communication and collaboration; the speed of cross-border conversations is nearly instantaneous.
  • New ethical and practical implications arise from digital media: misinformation, authenticity, and the manipulation of public opinion.
• The interplay of technology, literacy, and access remains central:
  • Even as more people gain access to information historically, disparities persist in literacy, digital access, and critical evaluation skills.
• The lecturer’s closing thoughts and forward-looking note:
  • Expectation of continued evolution in communication technologies (AI-generated content, digital media, etc.) and ongoing debates about media literacy, trust, and governance.
  • A reminder that history is messy and uneven, not a linear march toward enlightenment; “spotlights” illuminate different periods depending on what was preserved and who recorded it.
• Final reminder about Wednesday’s class:
  • The session will continue with more content and examples, potentially including a deeper dive into religion’s role in public life and more on early media.

Key takeaways for exam-style study

• Technology is a driver of social organization. Writing is a technology; money is a technology; both shape how societies interact and how power is distributed.
• Media evolve from private letters to public notices, to mass media (printing, newspapers, broadcasting) and now to digital networks; each leap changes who can participate in public discourse and how information spreads.
• Literacy is not universal; where literacy is limited, imagery and ritual play dominant roles in communication and social cohesion.
• Access to information is historically contingent: wealthy elites have accessed knowledge first, with libraries and public institutions gradually expanding access for broader populations.
• Religion and politics are deeply intertwined; public religion, ritual sacrifice, and belief systems influence governance, law, and social norms across civilizations.
• Syncretism and homogenization describe how deities and religious ideas travel and adapt across cultures, shaping how people conceptualize power, disease, weather, and justice.
• Modern concerns about verification, misinformation, and AI echo ancient anxieties about who controls knowledge and how it is interpreted by the public.
• Always interpret historical communication as a mosaic: periodization, language access, and media ecology determine what information survives and how it is understood.

Connections to broader themes and real-world relevance

• Information is power: access to libraries, printed material, and mass media historically correlates with social and political influence.
• Technology and literacy co-evolve: innovations lower costs and barriers to information, but also create new needs (critical literacy, media verification) to maintain trust.
• Public discourse is contingent on media ecology: the same message behaves very differently when delivered as scrolls, broadsheets, radio, or social media.
• Ethical implications of AI and media manipulation: authenticity, accountability, and critical evaluation are central in both ancient and modern contexts.

Notable dates, terms, and figures mentioned (quick reference)

• Movable-type printing: Gutenberg’s technology (late 15th century) vs earlier Chinese movable-type by ~500 years ahead of Gutenberg in terms of concept rough timeline.
• Public libraries: Andrew Carnegie’s library program funded roughly 2{,}509 libraries.
• Public messaging formats: acta diurna (Roman), tapǔ (Chinese public notices), medieval broadsheets, early newspapers.
• Transportation milestones: relay horse systems enabling ~15\,\text{miles} per leg; ~20\text{ minutes} per leg for galloping horses; total relay distance contributing to a week-long message delivery between distant capitals; Pony Express as a later cultural benchmark.
