Public relations is the discipline of building and protecting reputation through earned communication — coverage and credibility you do not pay for. It combines media relations, crisis communications, executive communications, content, and the broader set of practices that shape how organizations are understood by the publics that matter to them. The discipline traces to Ivy Lee in 1906 and Edward Bernays in 1923, was institutionalized by the Public Relations Society of America in 1947, and operates today as a roughly $130 billion global industry.
I have published Everything-PR since 2009. I have run 5W since 2003. Across more than two decades and two best-selling editions of For Immediate Release, I have watched the discipline survive the collapse of newspapers, the rise of social platforms, the maturation of digital marketing, and the constant pressure to confuse public relations with the louder, paid disciplines that sit next to it.
Public relations did not change at its core. The channels carrying it did.
This is the definitional reference on what PR is, where it came from, and what it does.
The Definition
The Public Relations Society of America defines PR as "a strategic communication process that builds mutually beneficial relationships between organizations and their publics." The Chartered Institute of Public Relations defines it as "the discipline which looks after reputation — the result of what you do, what you say, and what others say about you."
Both definitions are accurate. The field has many specialties. The audiences are varied. The channels are different across categories. But the foundation is the same — earned influence through credible third parties, anchored in the relationships and the reputation a company has built over time.
What Public Relations Does
Media relations
Building and maintaining relationships with journalists, editors, and producers. Pitching stories. Placing coverage. Managing interview access. The original core of the discipline. The publications and reporters who cover a category determine, more than any other single factor, how that category is understood by the public.
Reputation management
Shaping what key audiences believe about the organization. Monitoring what is being said. Correcting what is wrong. Building the credibility that sustains the company through the inevitable hard period. The reputation a company holds at the moment of a difficult news cycle is the reputation it built across the years before it.
Crisis communications
Managing the organization's response when something goes wrong. Quickly. Accurately. With accountability. Crisis communications is where every prior investment in media relationships, executive credibility, and stakeholder trust either holds or fails. See EPR's Crisis PR pillar for the discipline in depth.
Executive communications and thought leadership
Producing the primary-source material — articles, research, speeches, reports — that builds authority. A CEO who is known for substantive contribution to the category is a CEO whose company receives a different level of attention from press, analysts, recruiting candidates, and customers.
Stakeholder communications
Investors. Employees. Government. Communities. Industry partners. Each audience requires its own voice and cadence. Each compounds — or undermines — the others. Strong companies build the disciplines to manage each independently while keeping the overall narrative coherent.
Public affairs and issues management
Shaping the policy and regulatory environment. Influencing how rules get written, not just how the organization operates under them. Public affairs is among the highest-leverage applications of PR for large companies operating in regulated industries.
What PR Is Not
PR is not advertising
Advertising is paid. Controlled. Declared. The audience knows it is an ad and discounts it accordingly. PR is earned — a journalist independently decides the story is worth telling. The credibility differential is why a favorable Wall Street Journal feature moves a stock price and a full-page ad in the same section does not. The Tylenol recall of 1982 restored the brand not because Johnson & Johnson bought its way back into consumer trust, but because independent reporters covered the company's decision to pull 31 million bottles at a cost of $100 million and call it what it was.
PR is not marketing
Marketing is the full effort to create and deliver value to customers — paid media, owned content, positioning, pricing, distribution. PR is specifically the earned channel inside that stack. Costco has run one of the most valuable brand-building operations of the last forty years while spending almost nothing on traditional advertising — the wages the company pays, the 92%+ membership renewal rate, and the press coverage those two things generate do the work marketing would otherwise pay for. The disciplines overlap. They are not interchangeable.
PR is not spin
Spin — the selective presentation of facts to mislead — is an ethical violation, not a PR practice. The PRSA Code of Ethics requires honest and accurate representation. Every crisis that turned catastrophic — from Volkswagen's Dieselgate concealment to Boeing's early 737 MAX response — turned catastrophic because the company treated communications as the defense of a bad position rather than an honest account of what happened. Truth surfaces. Companies that argue with it lose twice.
Where Public Relations Came From
Modern PR traces to the early 20th century.
Ivy Lee — often called the father of PR — developed the practice of open corporate communication with media around 1906. A significant departure from the secrecy that characterized big business communications at the time. Lee worked for the Pennsylvania Railroad and later for the Rockefeller family. He argued that companies were better served by giving reporters honest information than by withholding it.
Edward Bernays, Lee's contemporary and the other foundational figure, brought social science into PR practice. He applied psychological principles to communications strategy. His 1923 book Crystallizing Public Opinion first articulated PR as a profession. He taught the first university course on public relations at New York University the same year.
The mid-20th century institutionalized the discipline. The Public Relations Society of America was founded in 1947. Codes of ethics were established. Practice expanded from press agentry into the full spectrum of corporate, political, and nonprofit communications.
The late 20th century built the global agency tier — Hill & Knowlton (founded 1927), Burson-Marsteller (1953, now Burson), Edelman (1952). Crisis communications, investor relations, and public affairs became distinct disciplines with their own playbooks, their own bench of senior practitioners, and their own measurement standards.

The PESO Model
PESO — Paid, Earned, Shared, Owned — is the standard model for understanding how PR fits into the broader communications stack. Earned media (the PR domain) sits alongside paid advertising, shared social, and owned content as complementary channels with distinct strengths. The most effective programs run all four. Paid amplifies earned. Owned content feeds media pitching. Shared extends reach. Earned anchors credibility.
The framework is taught in every serious PR education program because it is the cleanest way to explain where the discipline's leverage actually sits — earned is where credibility lives, and credibility is what PR is in the business of building.
The Global PR Industry
The global PR industry generates roughly $130 billion in annual revenue, split across in-house corporate functions and the agency tier. The largest independent is Edelman. The largest holding-company networks are Weber Shandwick (IPG), FleishmanHillard (Omnicom), and Burson (WPP). The U.S. independent tier includes 5W, Finsbury Glover Hering, Brunswick, and Joele Frank, with specialty practices across consumer, corporate, financial, and crisis.

Why PR Matters
Reputation is a strategic business asset. Organizations with strong reputations command pricing power, attract better talent, hold investor confidence through difficult quarters, receive more favorable regulatory treatment, and recover from crises faster than companies that built none of that infrastructure. These are measurable financial outcomes. Not soft brand effects.
PR is the function responsible for building and protecting that asset. In a media environment where a single story can reach millions in hours, where employee reviews are public, and where the press still sets the terms on which categories are debated, the companies investing in communications are building durable advantage. The ones treating it as an afterthought are accepting risk they may not be able to afford when it surfaces.
PR is one of the cheapest forms of long-term equity a company can build. The cost of doing it well is small. The cost of not doing it at all is large, deferred, and almost always invisible until the moment it shows up. See PR Is a Business Strategy, Not a Line Item and Is PR Important?
