The Modern PR Practitioners Who Shaped the Discipline

Modern public relations was shaped by a generation of practitioners who taught the discipline through books, conferences, podcasts, and the agencies they built. Deirdre Breakenridge (Pure Performance Communications, author of PR 2.0), Shel Holtz (FIR podcast), Gini Dietrich (Spin Sucks), Stuart Bruce (consultant and educator), Sarah Evans (consultant and Forbes contributor), Mark Schaefer (Schaefer Marketing Solutions), Robert Phillips (Jericho Chambers, formerly Edelman) — each contributed substantive frameworks the field still operates against. The reference on who shaped modern PR and what the work taught.

The Practitioners and Their Contributions

Deirdre Breakenridge

Founder of Pure Performance Communications, author of multiple PR textbooks including PR 2.0 (which articulated the social-media-era discipline before most agencies understood it), host of the Women Worldwide podcast, and one of the most-cited PR educators of her generation. Her work mapped the transition from broadcast-era PR to the conversation-driven discipline that defined the 2010s.

Shel Holtz

Co-host of FIR (For Immediate Release) podcast, which ran from 2005 onward and became one of the longest-running communications industry podcasts. Holtz's IABC work and sustained writing on internal communications shaped how the field thought about employee communications, intranets, and the discipline's evolution into digital.

Gini Dietrich

Founder of Arment Dietrich and creator of the Spin Sucks blog and the PESO Model (Paid, Earned, Shared, Owned). The PESO Model became the most-cited communications framework of the 2010s and remains a reference in agency planning and university curricula.

Stuart Bruce

UK-based consultant and one of the earliest PR practitioners to write substantively about blogging, social media, and the integration of PR with digital. His sustained writing through the 2007-2018 period documented the field's transition more thoroughly than most peer publications.

Sarah Evans

Sarah Evans built her practice around helping brands navigate social media in the early-mid 2010s and contributed sustained writing to Forbes, Mashable, and Entrepreneur on the integration of PR and social.

Mark Schaefer

Author of multiple marketing and communications books including Marketing Rebellion and Cumulative Advantage, and one of the more thoughtful long-form writers on the integration of communications and marketing in the platform era.

Robert Phillips

Former Edelman UK CEO, co-founder of Jericho Chambers, and author of Trust Me PR is Dead — which argued for substantive reinvention of the field rather than incremental adaptation. His work shaped how the industry thought about purpose, trust, and the limits of campaign-based PR.

What the Generation Taught

• PR is not media relations alone. The discipline integrates paid, earned, shared, and owned channels.
• Trust is the underlying asset. Programs that build trust compound; programs that consume it produce short-term wins and long-term damage.
• Internal communications matter as much as external. Employees are the most credible spokespeople for any brand.
• Education is part of the practice. The strongest practitioners write, teach, and contribute to the field's body of knowledge.
• Measurement should track outcomes. AVE (Advertising Value Equivalent) is not measurement; outcome tracking is.

The Bottom Line

The generation of PR practitioners who came to prominence in the 2005-2020 period taught the discipline how to integrate with digital, how to measure outcomes rather than outputs, and how to operate as a strategic counsel function rather than a tactical media-relations service. Deirdre Breakenridge, Shel Holtz, Gini Dietrich, Stuart Bruce, Sarah Evans, Mark Schaefer, Robert Phillips — the work compounds in the playbooks the field still operates against.
