Technologies and infrastructures
- Print networks: Trade and city directories such as Kelly’s in Britain and the Thomas Register in the United States indexed firms, trades, contacts, and addresses, and functioned as national B2B lookup engines. Kelly’s dominated London and regional markets through the early 20th century. Thomas Register expanded industrial categories through the 1920s and 1930s. catalog.hathitrust.org+3Wikipedia+3thelondonarchives.org+3
- Credit and reputation systems: R. G. Dun & Co. credit ledgers and later Dun & Bradstreet reference books provided firm level profiles and risk ratings used by merchants and banks, a pre-digital analog to trust and verification. library.hbs.edu+1
- News and wire services: The discovery layer of global information ran through the Havas–Reuters–Wolff oligopoly, later joined by AP and others, which distributed reports to newspapers and bulletins. This produced shared agendas and fast syndication. cepii.fr+1
- Professional communities: The Institute of Radio Engineers (IRE) and similar bodies circulated proceedings, standards, and member lists, which served as sector specific networks with publication based visibility. ETHW+2World Radio History+2
- Broadcast schedules and guides: The Radio Times, founded 1923, standardized program listings and became a weekly reference product with editorial curation, photography, and advertising. It is a period touchstone for feed like sequencing and placement. Wikipedia+2radiotimesarchive.co.uk+2
- Catalog commerce and sponsorship: Sears catalogs and emerging department stores in 1925 blended merchandising, advertising inventory, and mail order fulfillment, a model for promoted placements and paid discovery. archives.lib.duke.edu+1
Cultural movements and constraints
- Colonial press systems and languages of administration shaped who could publish, translate, and be amplified.
- Gatekeeping sat with editors, directory compilers, chamber of commerce officers, and censors.
- Telegraph and postal systems created measurable costs per contact. This encouraged concise profiles, references, and introductions.
Key Findings
- Directories, credit books, and professional proceedings together provided the core primitives of profile, verification, and discovery. Wikipedia+2library.hbs.edu+2
- Wire agency oligopolies functioned as global ranking and agenda setters for what appeared “in feed.” cepii.fr
- Catalogs and program guides demonstrate inventory like placement and sponsorship that map cleanly to paid reach. archives.lib.duke.edu+1
| Modern Feature | 1925 Analog | Why this maps | Constraints (tech or social) | Source Hook |
|---|---|---|---|---|
| Personal profile | Trade directory entry plus calling card plus chamber yearbook listing | Directories standardize name, trade, address, and sometimes brief blurbs; cards carry branding and contact method; yearbooks add association status and committees | Pay to list, geographic bias, compiler discretion, delays between editions | Kelly’s Directory and London trade directories; Thomas Register notes on category coverage growth in 1920s |
| Connections graph | Letters of introduction and association membership rolls | Introductions documented provenance and trust; membership rolls made ties legible and searchable | Access filtered by class, race, gender, and colonial status; slow verification | IRE membership structures and local sections |
| News Feed (algorithmic) | Editorial page flow plus wire copy placement plus club bulletins | Editors sequenced items by perceived importance; wire priorities and bulletin order produced a quasi ranking experience | Oligopoly of sources; editor bias; advertiser influence | Havas–Reuters–Wolff oligopoly; newsroom practice studies |
| Company Pages | “House organs” and catalog pages; trade advertisements in directories | Firms published magazines and catalog sections to present products, personnel changes, and announcements | Cost of print runs; distribution limits; claims policed by libel norms | Sears catalogs; directory advertising practices |
| Job postings | Newspaper classifieds; association circulars; employment bureaus | Classifieds provided roles by trade and city; associations circulated vacancies to members | Pay per line; local reach; discriminatory practices common | Newspaper and association circular conventions [source hint – verify] |
| Endorsements & Recommendations | Testimonials, reference letters, and D&B credit remarks | Testimonials attached to ads; letters of reference traveled with applicants; credit ledgers recorded reliability | Often private or semi private; liable to bias and retaliation | R. G. Dun & Co. credit volumes; D&B Reference Book |
| Skills & Badges | Guild certificates, association grades, examination results | Skills codified by certificates and society grades; publishable in yearbooks | Credential access unequal; recognition varies by region | IRE grades and standards activity |
| Messaging & InMail | Telegrams, postcards, business letters via typed correspondence | Paid per message cost disciplines outreach; telegraph for urgency; post for routine | High friction; office hours; secretarial mediation | Western Union practices and artifacts [source hint – verify] |
| Groups | Club newsletters and meeting minutes, eg. radio clubs, Rotary | Regular meetings with minutes and member lists mirror topical groups | Membership vetted; minutes curated; geography bound | Proceedings of IRE; club bulletins |
| Ads, Sponsored posts | Display ads in directories, catalogs, and program guides | Paid placement adjacent to high attention sections; long tail classifieds for SME reach | Rate cards, layout constraints, and reader fatigue | Radio Times ad layouts and growth; Sears ad mix |
| Creator Mode & Articles | Trade press columns, technical notes, and proceedings papers | Individuals gain status by contributing articles and notes; editorial selection is the gate | Long lead times; strict style; fees or dues | Proceedings of the IRE |
| Verification checkmark | Listing provenance plus D&B identity, plus association membership number | Verified through paid listings, credit files, and society records | Errors persist until next print run; forgery risk; exclusionary | D&B and association registries |
| Events & Webinars | Trade fairs, society lectures, radio talks listed in Radio Times | Timetabled listings with venue details, sometimes sponsored by firms | Travel cost; urban bias; limited capacity | Radio Times schedules |
Key Findings
- LinkedIn’s primitives map cleanly to four 1925 substrates: directories, associations, wires, and catalogs.
- Ranking equals editorial judgment shaped by wire inputs and advertiser pressure rather than behavioral signals. cepii.fr
- Verification and endorsements live in slow moving ledgers and letters, which raises costs and lowers spam.
Ranking and discovery
- Source flow: City and trade papers pull from wire agencies, then editors place copy and paid notices. This determines what most professionals “see” first, which functions like a coupled “Top” and “Following” feed. cepii.fr
- Directory search: Queries are resolved by indexers and subject headings. Discovery quality depends on the compiler’s taxonomy and the buyer’s advertising spend. Wikipedia+1
- Authority signals: Society grades, bylines in proceedings, and letters of reference add weight. Presence in D&B reference books stabilizes identity in B2B contexts. ETHW+1
Moderation and policy
- Gatekeeping: Editors enforce libel and taste norms; association secretaries accept or reject notices; colonial censors block hostile publications.
- Discipline of cost: Per line advertising and per word telegram pricing throttle volume, which reduces low quality or mass unsolicited contact.
- Reputation consequences: Negative or absent D&B notes constrain access to credit and partnerships, similar to shadow trust scores. The Library of Congress
Monetization
- Listings revenue: Paid directory entries, boldface upgrades, and category cross listings mirror paid profile boosts. thelondonarchives.org
- Display and classifieds: Ad inventory adjacent to popular sections, catalog placements, and sponsored program listings map to Sponsored Content and Display Ads. archives.lib.duke.edu+1
- Events: Ticketed lectures and fairs serve as lead generation with sponsorship bundles.
Data limits and feedback loops
- No behavioral telemetry beyond letters to the editor, coupon returns, or sales. Adjustment cycles are quarterly or annual at best.
- The feedback loop is editorial reputation and advertiser renewals, not click through rates.
Key Findings
- “Algorithm” in 1925 is a mix of taxonomies, editorial ordering, and price schedules.
- Cost structures act as built in spam filters.
- Reputation artifacts substitute for engagement metrics, and they update slowly. The Library of Congress
Before I proceed to 4) User Experience & Journeys through 11) Further Reading & Sources, please confirm:
- Do these mappings for LinkedIn → 1925 feel correct for your intent, or should I bias more toward radio clubs and broadcast culture versus directories and trade press?
- Any regional emphasis you want in the upcoming vignettes, for example India, Japan, West Africa, or Latin America?
- Do you want me to add a short rate card box for classifieds and telegrams to quantify the “cost as anti spam” mechanism?
The directory and trade press approach is solid, but I'd like to see more on radio clubs and broadcast culture to show how group identity and real-time connections worked during that period. For the regional focus, please include clear examples from India, Japan, and West Africa. Latin American perspectives would also help highlight global differences. It’s important that at least one story covers language or colonial barriers in professional networking.
Yes, please add a simple rate card for classifieds, telegrams, and membership so we get a feel for the real costs and the way these systems limited spam and open access.
Thanks, and go ahead with the next steps.
An electrical draftsman in Bombay listens to the Bombay Presidency Radio Club’s evening broadcast, then visits the club room to post a typed notice on the board: “Seeking junior post in traction motors; references available.” He also mails a short classified to The Times of India and sends a 12-word inland telegram to a Calcutta manufacturer introduced through a cousin. The Calcutta Radio Club publishes next month’s lecture list, where he plans to hand out calling cards that cite his club membership. The rhythm is weekly and monthly, not real time. Discovery flows through station schedules, club bulletins, small classifieds, and paid telegrams. gbps.org.uk+4prasarbharati.gov.in+4DAV University+4
A student tinkers with shortwave coils, hears call signs from Hokkaido, and exchanges QSL cards. In 1926 he joins the newly formed Japan Amateur Radio League and appears in the first JARL NEWS bulletin. His “profile” is a membership entry with call sign, grade, and club section. Discovery is word of mouth at meetings, printed rolls, and station lists. Authority signals are society affiliation and on-air etiquette. Paid placement is a small display ad for valves in the back of a technical monthly. jarl.org+1
A clerk in Accra drafts a notice for an engineers’ study circle in English and Ga, but the local wire service only carries English. In 1935 a wired relay station opens in Accra and schedules are posted at the post office. Notices must comply with colonial rules, and minutes circulate through expatriate networks faster than local ones. A Sierra Leone contact hears a BBC Empire relay and writes back with interest, but postage and telegraph costs slow the exchange. The clerk adds a line to his calling card: “Ga and English.” gbcvoice.com+2jstor.org+2
A physics teacher hears Rádio Sociedade’s cultural program and mails a short note praising a lecture. He pays for a small classified offering evening tutoring and lists his professional society number. The station’s house bulletin prints selected listener letters, which function like public endorsements. A local manufacturer sponsors a series on technical trades and invites him to speak, which becomes a durable “portfolio item” when clipped and saved. UNESCO+1
Examples (period-plausible tone)
Post: “Junior engineer, trained in DC traction motors and shop drafting, seeks placement. References enclosed. Available Bombay–Calcutta travel in July.”
Profile: “Member, Bombay Presidency Radio Club. Draftsman, 2 years. Studies in applied electricity. Languages: Marathi, English. References: Mr. R—, mill electrician; Mr. B—, tramways.”
Feed excerpt:
- “JARL bulletin: new call sign allocations J1–J9 announced.”
- “Gold Coast relay station opens, evening news at 8.”
- “Rádio Sociedade education hour seeks contributors in science.”
Key Findings
- Clubs and stations add group identity and quasi real time presence through schedules, call signs, and meetings.
- The “profile” is membership plus printed identifiers; messaging is telegrams and letters with per-word costs.
- Language and colonial rules shape reach and tone, especially in West Africa. gbcvoice.com
- India: Early broadcasting is club-led. The Bombay and Calcutta Radio Clubs in 1923 precede state broadcasting. Notices move through club bulletins and newspapers; telegrams supply urgency. prasarbharati.gov.in+1
- Japan: JARL forms in 1926, builds national sections, and issues bulletins with call signs and technical notes. Membership rolls function as a discovery layer with reputational norms. jarl.org
- West Africa: Broadcasting arrives through colonial infrastructure in the 1930s, with relay stations and later services in Accra and Sierra Leone. Content and publicity are filtered through colonial policy and English-language preference, limiting local languages. gbcvoice.com+2qiraatafrican.com+2
- Latin America: Brazil’s Rádio Sociedade (1923) blends civic mission, education, and cultural prestige. Clubs and associations cross-publish program notes and professional opportunities. UNESCO+1
Language and translation
- Administrative languages dominate official notices. Translation to Ga, Yoruba, or Quechua is rare or informal. West African and Indian journals sometimes print bilingual items, but fee schedules and telegram forms reinforce English. ResearchGate
Key Findings
- Group identity is enacted through call signs, sections, and club minutes.
- Colonial and administrative languages gate access to visibility and jobs.
- Regional maturation timings are staggered, which changes who “gets seen.”
Materials and typography
- Directories and club bulletins: Letterpress, narrow columns, condensed grotesques or small serifs; rules and hairlines define sections.
- Radio listings: Program grids similar to Radio Times with time blocks, station codes, and small display ads. Wikipedia
- Latin America: Educational house organs pair humanist serifs with decorative drop caps. UNESCO
- Japan: Vertical Japanese alongside roman call signs in bulletins, with simple grids. jarl.org

(Optional) Network sketch: Sections connect via arrows to stations; edges represent introductions or QSL exchanges.
Key Findings
- The visible surface is a composite of program grids, club notices, and small ads.
- Profiles are compact cards tied to clubs and postal identities.
- Visual hierarchy privileges schedules and official sections, not infinite scroll.
- Propaganda: West African broadcasting grows within imperial information strategies by the mid-1930s. Listings and bulletins fold official narratives into daily consumption. Cambridge University Press & Assessment
- Surveillance: Gatekeepers include club secretaries, censors, and wire editors. Letters of introduction and credit ledgers leave paper trails that echo “trust scores.” The Library of Congress
- Inequality: Membership dues, telegraph rates, and ad line costs exclude many. Administrative languages elevate certain voices.
Controversy vignette
In 1935 Accra, a relay schedule lists “industrial opportunities” sourced from a London trade paper. Local engineers protest that qualifications ignore Gold Coast apprenticeships. A letter to the editor in English is printed, but a Ga translation is refused as “space constrained.” The governor praises the new service as “inclusive,” while clubs quietly add side lists in local languages. gbcvoice.com
Key Findings
- Information power sits with editors and colonial administrators.
- Price and language are structural filters.
- Clubs mitigate exclusion but cannot remove it.
- India: Private clubs give way to the Indian Broadcasting Company in 1927, which collapses, then state broadcasting reforms and later becomes All India Radio in 1936. Club identity persists as a parallel layer. Wikipedia
- Japan: JARL formalizes call signs, hosts conventions, and joins the IARU. Technical capacity and spectrum organization professionalize the network. jarl.org
- West Africa: Relay and early services arrive by mid-1930s, often for imperial news in English. Local language initiatives grow slowly, limited by policy and resources. gbcvoice.com+1
- Latin America: Educational broadcasters in Brazil stabilize, with house organs and cultural missions forming reputational pathways that stand in for “creator mode.” UNESCO
Key Findings
- By 1935, the “platform” shifts from club-centric to more state and corporate layers.
- Standardization strengthens credentials but narrows informal pathways.
Scenario: Telegram rate shock and print recession, 1929–1931
If telegram rates rise while classifieds contract, unsolicited outreach collapses. Clubs respond by expanding noticeboards and low-cost bulletins. Radio listings become the discovery spine, with sponsorship substituting for ad classifieds. Result: higher reliance on group identity and curated referrals, lower mobility for those outside clubs. [source hint – verify]
Key Findings
- Cost shocks push the network toward closed groups.
- Sponsorship replaces open classifieds, reducing “cold” discovery.
Summary bullets
- LinkedIn in 1925 sits on four pillars: radio clubs, program guides, directories, and credit/reference ledgers.
- Real time is scheduled time: weekly bulletins and nightly programs.
- Ranking equals editorial sequencing plus taxonomy, not clicks.
- Verification is membership roll + credit reference, updated slowly.
- Inequality is baked in through dues, rates, and language policy.
- 1935 brings consolidation: state broadcasters, formal societies, and relay networks.
- Clubs remain the social glue that simulates groups and messaging.
Implications for Today
The 1925 reconstruction shows how costs, schedules, and gatekeepers shape “algorithmic” visibility. Replace per-word telegram fees with API and ad prices and the pattern is familiar: outreach is rationed by money and access, not only by engagement. Clubs and sections prefigure groups and professional communities. They also illustrate how identity is carried by institutional affiliation and credential signals rather than behavior logs.
Radio clubs demonstrate a workable model for healthy group identity: visible rules, mentors, and a culture of reply via QSL and minutes. The risk is enclosure. When price and policy harden, discovery narrows to those who can afford the dues or master the administrative language. Modern platforms face the same tension between open discovery and pay-to-reach dynamics, especially across languages and regions with weaker ad markets.
Implications for Global Media History
This lens corrects archive bias that favors Anglo-American newspapers. Latin American educational broadcasting and Japan’s JARL show alternative genealogies of professional networking. West African timelines reveal how colonial infrastructures delayed or redirected local professional visibility. Platform studies benefit from aligning features with concrete media ecologies rather than assuming a single Western lineage.
Discussion Questions
- What would a modern “club-first” professional network look like if outreach carried a small, explicit per-message cost?
- How can platforms reward multilingual postings and local credentials without recreating colonial language hierarchies?
- Which present-day verification signals could be decoupled from paid tiers and re-anchored in community institutions?

- Society publishing: IRE Proceedings subscription for non-members around $9 per year in the late 1920s; membership grades carried separate dues. Use as a proxy for professional access cost. World Radio History
Why this matters
Per-word and per-line pricing created natural throttles on unsolicited outreach. Society dues and subscriptions set a bar for participation. Together these costs function like anti-spam friction and paid tier visibility.
Key Findings
- Clubs and stations meaningfully extend the original directory logic by adding live schedules, shared identity, and reciprocal etiquette.
- India, Japan, West Africa, and Brazil supply distinct but comparable pathways into professional visibility.
- The clearest modern lesson is that a little friction, applied fairly and multilingual by design, can raise quality without reproducing historical exclusions.
- ✅ Inputs confirmed and defaults applied.
- ✅ Features derived from LinkedIn, not preset examples, and extended to radio clubs.
- ✅ ≥ 3 primary sources with citations.

- ✅ Mapping table and ASCII mockups included.
- ✅ Inequality, coloniality, and surveillance analyzed.
- ✅ Evolution and counterfactual covered.
- ✅ Discussion and implications completed.
- ✅ Clean Markdown, no filler.
If you want, I can add a one-page “spec sheet” summarizing club structures, typical schedules, and a visual of the discovery pipeline with the rate card embedded.
