AP HG Unit 3 · Lesson 6 of 8CED 3.6Skill 5.B~ 55 min

Contemporary Causes of Diffusion

Today, urbanization, globalization, and communication technologies do most of the work that colonialism, imperialism, and trade once did. They diffuse culture faster, farther, and at smaller scales — producing both convergence (the same brands and platforms everywhere) and divergence (revitalized local identities and endangered languages).

Learning Objectives

By the end of this lesson, students will be able to (per CED LO SPS-3.A, EKs A.3 and A.4):

  • Identify the contemporary forces that drive cultural diffusion: urbanization, globalization, media, technological change, politics, economics, and social relationships (per EK SPS-3.A.3).
  • Explain how communication technologies and time-space convergence reshape and accelerate interactions among people (per EK SPS-3.A.4).
  • Distinguish cultural convergence from cultural divergence as the two contradictory outcomes the CED names explicitly.
  • Identify the global rise of English as a contemporary diffusion phenomenon and connect it to the loss of indigenous languages (per EK SPS-3.A.4).
  • Apply Skill 5.B: explain a contemporary diffusion outcome across multiple geographic scales (global, national, local).

Key Concepts

Per CED EK SPS-3.A.3, "cultural ideas and practices are socially constructed and change through both small-scale and large-scale processes such as urbanization and globalization. These processes come to bear on culture through media, technological change, politics, economics, and social relationships." Per CED EK SPS-3.A.4, "communication technologies, such as the internet and the time-space convergence, are reshaping and accelerating interactions among people; changing cultural practices, as in the increasing use of English and the loss of indigenous languages; and creating cultural convergence and divergence."

How "contemporary" is different from "historical"

Topic 3.5 covered colonialism, imperialism, and trade — forces with centuries-long timescales and physical displacement of people, goods, or armies. Topic 3.6 covers forces that operate at much faster speeds and across smaller social distances. A meme can travel the world in hours. A Korean drama can spawn thousands of new fans in a city that has never had a Korean diaspora. The mechanisms remain the four diffusion types from Topic 3.4 — but the speed and reach have changed dramatically.

"Communication technologies — the internet and the time-space convergence among them — are reshaping and speeding up human interaction, altering cultural practices (the spread of English and the loss of indigenous languages, for example), and producing both cultural convergence and divergence."AP HG CED, EK SPS-3.A.4 (paraphrased)

Time-space convergence

Time-space convergence is the shrinking of perceived distance between places due to faster transportation and communication. The phrase comes from geographer Donald Janelle (1968). A trip from New York to London took ~6 weeks by sailing ship in 1800, ~6 days by steamship in 1900, ~6 hours by jet today, and ~0 seconds by internet for information. Two places that are physically far apart can now be experientially close. This is the engine behind much contemporary diffusion.

The Contemporary Forces

Per CED EK SPS-3.A.3 and EK SPS-3.A.4, the CED names urbanization, globalization, media, technological change, politics, economics, and social relationships as forces. Plus the time-space convergence concept and the internet specifically.

Urbanization

Cities mix people from many cultural backgrounds in close contact, accelerating diffusion. Modern megacities are nodes where global cultural practices first land and from which they spread to the country.

~57% of humanity now urban (UN)

Globalization

The increased flow of goods, capital, people, and ideas across borders. Multinational corporations, global supply chains, and international institutions diffuse cultural traits along economic networks.

McDonald's in 100+ countries; Apple, Samsung worldwide

Internet & Communication Tech

The internet, social media, and mobile platforms enable diffusion at the speed of light. Viral videos, online religion, fandoms, and political movements all use the same global infrastructure.

~5.4 billion internet users (~67% of humanity)

Time-Space Convergence

The shrinking of perceived distance due to faster transport and communication. Janelle's (1968) concept. The same trip that took weeks in 1800 takes hours today; the same conversation takes seconds.

NY→London: 6 weeks (1800) → 6 hrs (today)

Politics, Economics, Social

Per EK SPS-3.A.3, politics (immigration policy, free trade agreements), economics (multinational labor flows, tourism), and social relationships (transnational families, diaspora communities) all diffuse culture.

Tourism, remittances, EU labor mobility

Media

Film, television, music, and now streaming services move cultural content across borders. Hollywood, Bollywood, K-drama, anime, and global pop music all diffuse through media.

Squid Game, Money Heist, Naruto: global streaming hits

Cultural Convergence vs Divergence

Per CED EK SPS-3.A.4, communication technologies create both cultural convergence and cultural divergence. The pairing is intentional. The same internet that spreads global English also lets a Welsh-speaking teenager find a community of other Welsh speakers. The CED expects students to see both sides.

Cultural Convergence

The pattern: Distant places start to share more cultural traits. Global brands, music, films, fashions, technology platforms, and English as lingua franca produce visible sameness across world cities.

Examples Same Starbucks, McDonald's, and H&M in airport malls from Singapore to Cape Town to Toronto. Hollywood films dominating box office worldwide. The rise of English in business, science, and aviation. Smartphones replacing many local communication forms.

Cultural Divergence

The pattern: Local, regional, or subcultural identities are strengthened, often as a deliberate response to convergence. The same internet that brings global culture also lets minority communities organize and revitalize.

Examples Welsh, Maori, Hawaiian, and Catalan language revitalization. Local food sovereignty movements (slow food, locavore). Religious revival movements (Christian evangelicalism, Islamic revival, Hindu nationalism). Niche subcultures organized through Discord, Reddit, TikTok.

The endangered language case

Per EK SPS-3.A.4, communication technologies cause "the increasing use of English and the loss of indigenous languages." Of about 7,000 living languages, roughly 40% are endangered. UNESCO estimates that one language dies approximately every two weeks. The cause is partly convergence (young speakers shift to dominant national languages for economic reasons), but partly divergence (where revitalization movements succeed, languages can recover — Hebrew is the most successful modern revival case).

Country Case Studies

Four cases that show contemporary diffusion forces and the convergence/divergence dual outcome.

South Korea flag

South Korea · Hallyu (K-Wave) Diffusion

~$13B cultural exports (2023)

The Korean Wave (Hallyu) is contemporary cultural diffusion at high speed. K-pop, K-drama, Korean cosmetics, and Korean food spread through internet platforms (YouTube, Netflix, TikTok) to global youth audiences. South Korea has become a major cultural exporter primarily through digital communication technology — not through colonialism or imperialism.

New Zealand flag

New Zealand · Maori Language Revival

~50% increase in Maori speakers since 1996

Te Reo Maori was nearly lost by the 1970s due to convergence pressure from English. New Zealand's deliberate divergence response — Maori-language broadcasting, immersion schools (Kohanga Reo), official language status, government promotion — has produced a revival. Cultural divergence in operation, using some of the same media tools as convergence.

China flag

China · Selective Convergence

~1.05B internet users (~75% of population)

China presents a partial-convergence case. Global brands (KFC, Starbucks, Tesla) thrive; global platforms (Google, Facebook, X) are blocked and replaced by Chinese equivalents (Baidu, WeChat, Weibo). Communication technologies do diffuse culture, but the Chinese state actively manages which directions diffusion can flow. A reminder that convergence is not inevitable.

Bolivia flag

Bolivia · Indigenous Language Defense

37 official languages (2009 constitution)

Bolivia's 2009 constitution recognized 36 indigenous languages alongside Spanish, an explicit divergence-strengthening move. Quechua and Aymara have official status; bilingual education is standard; courts use indigenous languages. The state policy uses contemporary tools (constitutions, education systems, broadcasting) to push back against the convergence pressure of Spanish.

Discussion Questions

  1. The CED's contemporary causes (urbanization, globalization, communication technology) are all 20th- and 21st-century phenomena. But colonialism, imperialism, and trade still operate. When does it make sense to call diffusion "contemporary" versus "historical"? Where is the line?
  2. Time-space convergence has shrunk the world dramatically over the past 200 years. Identify a specific cultural practice that exists today only because of time-space convergence (would not exist if travel and communication still took weeks).
  3. EK SPS-3.A.4 names two opposite outcomes: cultural convergence and cultural divergence. Pick one specific case (a city, a country, a language community) and identify both convergence and divergence happening there at the same time.
  4. The CED specifically names "the increasing use of English and the loss of indigenous languages" as effects of contemporary diffusion. What conditions cause an indigenous language to be lost? What conditions allow one to be revived?
  5. The internet is sometimes called "the great equalizer" of cultural diffusion because it lets small communities reach global audiences. Is that a convergence force or a divergence force? Use one specific example to defend your answer.

Classroom Activities

40 min

Time-Space Convergence Timeline

Pairs build a timeline of one specific NY-to-London (or other transcontinental) journey: by sailing ship (1800), steamship (1900), propeller plane (1950), jet (1970), and internet (today). They map each transit time, then write a short paragraph explaining how each speed change made new types of cultural diffusion possible.

Convergence/Divergence Map

Each pair picks one city. They identify three convergence markers (global brand, global media platform, global language) and three divergence markers (local language survival, ethnic neighborhood, traditional festival). They produce a side-by-side map and explain how the same city contains both forces simultaneously.
