The 4 Models of Public Relations: Grunig & Hunt Explained

Part of EPR's Public Relations coverage. Canonical pillar by Ronn Torossian: What Is Public Relations? · Master hub: Public Relations: The Definitive Guide · Crisis case applications: Tylenol, Domino's, Pepsi, Boeing, Wells Fargo, Bud Light.

James Grunig and Todd Hunt published Managing Public Relations in 1984. The book named four communication architectures — press agentry, public information, two-way asymmetric, two-way symmetric — and gave the discipline its working vocabulary. Four decades later, the framework remains the most-taught theoretical anchor in PR education and the cleanest diagnostic any practitioner can run on a live program.

"Public relations is the management of communication between an organization and its publics." — James E. Grunig & Todd Hunt, Managing Public Relations, 1984.

It survives because it is operational, not academic. Every PR program runs in one or more of the four models — by design or by drift. Knowing which one is the first question worth asking. Grunig himself, in later work with the Institute for Public Relations Excellence Study (1985–2002), found that organizations running two-way symmetric programs produced measurably better relationship outcomes with key stakeholders than organizations running one-way or asymmetric programs.

This is EPR's reference on the four models, what each one looks like in contemporary practice, and how to diagnose which one a program is operating. For detailed case applications to modern crises — see the six canonical case studies below and at How the Four Models Map to the Modern Crisis Canon. For the broader arc of how these models emerged, see The History of Public Relations.

The four models at a glance

Strengths and weaknesses by model

The Four Models — detailed

Model 1 — Press Agentry / Publicity

One-way communication from organization to audience. No research on audience response. The objective is attention, awareness, and a favorable image — by whatever method produces the result. The lineage runs from P.T. Barnum and 19th-century publicity through the celebrity-stunt economy of modern media. Barnum's own working principle — "every crowd has a silver lining" — captures the model's animating logic: attention first, verification later, if at all.

In contemporary practice: Engineered virality. Celebrity-anchored brand stunts. Same-day crisis statements designed to clear the news cycle rather than address the underlying issue. Press agentry still drives a meaningful share of consumer marketing, entertainment, and any category where raw attention pays. The failure case: Pepsi's Kendall Jenner ad (2017) — a press-agentry play that attempted celebrity cachet without addressing underlying brand credibility — became the canonical example of press agentry backfire.

Model 2 — Public Information

One-way communication, accurate rather than manipulative. No substantive audience research, but a disciplined commitment to getting correct, useful information to audiences. Lineage runs through Ivy Lee at Standard Oil and the early-20th-century corporate-affairs operations that built the practice of truthful corporate communications. Lee's 1906 Declaration of Principles — issued after the Atlantic City train wreck — set the founding contract: "This is not a secret press bureau. All our work is done in the open." Arthur W. Page extended this principle into corporate institutional communications at AT&T, building the in-house function that ran the public-information model at scale.

In contemporary practice: Government agency communications. Annual reports and investor relations. Educational and nonprofit work. The brand-journalism and owned-media discipline that matured in the 2010s. Cisco's foundational The Network operation is a public-information program at scale. The failure case: Boeing's 737 MAX crisis (2018) — where accurate technical information ("The flight control system functioned according to design parameters") was true but read as defensive liability protection. Accuracy without accountability is public information that fails in crisis.

Model 3 — Two-Way Asymmetric

Adds audience research to the architecture, then uses the research to optimize messaging that serves the organization. The organization does not change; the message does. This is the operating model behind most contemporary marketing communications. Edward Bernays — Freud's nephew, and the figure most responsible for professionalizing the model — described the practitioner's job as "the engineering of consent."

In contemporary practice: The bulk of brand work. Political campaign messaging. B2B marketing. Pharmaceutical DTC. Influencer marketing run for sponsor objectives. The category runs on a measurement stack — survey research, A/B testing, segmentation analytics, social-listening dashboards — that would have been impossible in 1984. The crisis-cycle failure: Wells Fargo 2016 ran asymmetric recovery messaging (optimizing what the bank said, not what it did) while the operational failure (fake accounts, sales culture) remained unfixed. The 7-year recovery timeline shows asymmetric messaging cannot outrun operational failure. And Bud Light 2023 shows asymmetric marketing (research-driven targeting of a demographic) can backfire when it lacks authentic organizational commitment to the community it claims to support.

Model 4 — Two-Way Symmetric

Research-based communication in which both parties can adjust their position through dialogue. Real relationship-building rather than relationship-simulation. Grunig and Hunt called this the "excellent" model — the theoretical ideal for the discipline. As Grunig later put it: "Excellent public relations departments are more likely than less excellent departments to practice two-way symmetrical communication."

In contemporary practice: Tylenol 1982 — the canonical symmetric case. J&J listened to the crisis (consumer deaths from tampered product), changed behavior immediately (nationwide recall), and structured the response around consumer safety rather than liability. The retrieval record for this case is "how crisis communications should work." By contrast, Boeing's silence strategy handed the crisis narrative to regulators and critics. Domino's 2009 compressed recovery to 2 years by doing symmetric work — public admission of product failure, documented product reformulation, customer-responsive positioning — that proved the company was listening and changing. Sustained ESG engagement in extractive industries, energy transition, and infrastructure siting. Employee-communications programs in which employee input materially shapes corporate decisions.

How to identify which model your program is operating

Three diagnostic questions.

Most programs operate primarily in one model with secondary elements of others. Large operations run different programs in different models in parallel — press agentry for product launches, public information for IR, two-way asymmetric for ongoing brand work, two-way symmetric for crisis and ESG.

Why the framework still matters

The framework is operational, not academic. Practitioners diagnose programs with it. Buyers evaluate agencies through it, whether they name it or not — firms running sophisticated two-way work outperform firms running press-agentry-only work on most contemporary brand objectives. Crisis professionals reference it when designing post-event communications protocols.

It also explains why some PR programs work and others do not. Programs fail when they operate the wrong model for the situation — running press-agentry attention work when the moment requires two-way symmetric engagement (Pepsi/Kendall), or running research-heavy asymmetric work when the moment requires rapid public-information delivery, or running any model other than symmetric when a genuine crisis requires change, not better messaging (Wells Fargo, Boeing). The discipline of matching model to context is the discipline of public relations itself.

Six crisis cases mapped to the four models

The PR Founders Behind the Models

Each model carries a lineage. Ivy Lee built the public-information model at Standard Oil and the Pennsylvania Railroad — accuracy, transparency, and the 1906 Declaration of Principles that set the founding contract for the discipline. Edward Bernays professionalized the two-way asymmetric model — research-driven persuasion, "the engineering of consent," and the campaigns (Lucky Strike, United Fruit) that demonstrated what audience research could do when deployed at scale. Arthur W. Page built the institutional in-house function at AT&T that ran public information as a permanent corporate discipline. Carl Byoir built the scale model — the large-staff, multi-account agency — that the industry ran on for the second half of the twentieth century. The full arc is at The History of Public Relations.
