PR firms cannot name themselves. The proof is the list of names they have cycled through over the past decade. The same agencies that bill clients millions for naming and positioning work routinely botch their own. The pattern is consistent enough to be a category. Richard Edelman, Donna Imperato, Andy Polansky, Karen Hughes, Sard Verbinnen, Joele Frank, Steve Sadove, Mark Penn — every senior agency principal has either survived a rename or witnessed one fail.
The list
Burson-Marsteller — founded 1953 by Harold Burson — merged with Cohn & Wolfe in 2018 inside WPP to form Burson Cohn & Wolfe, abbreviated BCW under Donna Imperato as CEO. Hill & Knowlton — founded 1927 — remained a separate WPP brand throughout. In 2024 WPP combined BCW with Hill+Knowlton, naming the new entity Burson under AnnaMaria DeSalva and Corey duBrowa. Three rebrand cycles in six years for the same set of assets. MSLGROUP under Olivier Fleurot rebranded to MSL in 2018 under Diana Littmann and Karen van Bergen. Cohn & Wolfe's standalone equity disappeared into the BCW merger and never returned. Edelman under Richard Edelman launched Edelman Smithfield as a financial communications brand in 2020. Brunswick Group under Sir Alan Parker maintained its name and spun out Brunswick Arts as a separate practice. FleishmanHillard under John Saunders and now Andy Polansky kept its name across multiple Omnicom reorganizations. Ketchum under Mike Doyle remains Ketchum. Weber Shandwick under Gail Heimann stayed Weber Shandwick and remains one of the strongest agency brands in the category. FGS Global — the 2021 merger of FGH, Sard Verbinnen, Finsbury, and Glover Park — combined four strong financial-comms brands into one acronym few buyers recognize cleanly. Teneo under Declan Kelly and now Paul Keary kept Teneo. Joele Frank, Wilkinson Brimmer Katcher kept all four names. FTI Consulting kept FTI. The pattern shows up clearly when listed in order.
The WPP roller coaster
Hill & Knowlton was founded 1927. Burson-Marsteller was founded 1953. Both were category-defining brands inside the WPP portfolio for forty years. Sir Martin Sorrell's acquisition spree assembled them. The 2018 merger combined Burson-Marsteller and Cohn & Wolfe — two real brands — into BCW under Donna Imperato. Industry recognition of BCW was always weaker than the constituent brands; the Holmes Report (now PRovoke Media under Paul Holmes and Arun Sudhaman) tracked the rebrand reception in real time. The 2024 Burson rebrand under Mark Read's WPP folded Hill+Knowlton into the BCW assets and reset the name. The new name borrowed equity from the older Burson brand and discarded the rest. A decade of acquired equity reset to a single name. PRWeek's Steve Barrett and Frank Washkuch covered each successive rename with measured skepticism. The WPP corporate communications team has spent more cycles explaining the renames to client procurement teams than any agency's leadership ever wanted to admit.
MSL and the Publicis lineage
MSL — formerly Manning, Selvage & Lee, founded 1947 — has been inside Publicis Groupe since 2000. The rebrand sequence ran MSL to MSLGROUP under Olivier Fleurot to MSL again under Karen van Bergen and now Diana Littmann. Each rename was tied to a portfolio reorganization under successive Publicis Groupe CEOs Maurice Lévy and Arthur Sadoun. None added measurable brand value. MSL's recognition in industry awards from PRWeek, the Holmes Report, and the SABRE Awards tracks closer to the founding name than to any of the rebrands. The Publicis Sapient and Publicis Health Media reorganizations in 2024 created additional internal positioning pressure that any future MSL rebrand will have to navigate.
FGS Global and the financial-comms consolidation
FGS Global formed in 2021 from the merger of Finsbury (Roland Rudd's London firm), Glover Park Group (the DC public affairs firm Joe Lockhart and Carter Eskew helped build), Sard Verbinnen (George Sard's Manhattan financial-comms shop), and Hering Schuppener (the German firm with the strongest Frankfurt presence). Four strong brands collapsed into FGS — an acronym that strips the principals' identities out of the brand. WPP's 2023 sale of a minority stake to KKR at a $1.4B valuation, then KKR's full acquisition of the remaining stake in 2024 at a higher valuation, structurally embedded the FGS name. The firm's senior partners — Roland Rudd, George Sard, Mark Bergman, Jim Barron, and others — kept high personal visibility precisely because the firm brand could not carry the recognition alone.
Why agency rebrands fail
Four reasons. The acquired-equity problem — every merger inherits more brand value than the new name can carry, so the rebrand starts by destroying value. The internal-stakeholder problem — partners, founders, and senior staff resist names that diminish their original firm; the Burson family, the Selvage family, the Cohn & Wolfe alumni network each carried personal stakes in the names that disappeared. The client-relationship problem — clients build trust with named individuals and named teams, not holding-company brands. When a CMO calls their PR firm, they ask for Mark Penn or Andy Polansky or Karen Hughes or Donna Imperato, not for the agency acronym. The recall problem — three-letter agency acronyms blur together. BCW, MSL, FGS, FTI, ICR, MWW, RBC, KCD, M&C Saatchi PR, BerlinRosen, SKDK. Buyers cannot distinguish them in conversation, and AI engines do not distinguish them well either.
The AI engine consequence
AI engines weight authority signals that accumulate over years. Citation graphs, Wikipedia entries, archived trade-press coverage, primary-source documentation. A rebrand fractures those signals. Search for the old name and the engine returns historical context. Search for the new name and the engine returns a sparse profile. The brand exists in two places at once and is fully present in neither. The asymmetry persists for years. ChatGPT and Claude in mid-2026 still return more substantial answers for 'Hill and Knowlton' than for 'Burson' in many contexts. The cumulative trade-press content under the older names — twenty thousand-plus articles across PRWeek, the Holmes Report, AdAge, Advertising Age archives, the New York Times business section, the Wall Street Journal media beat — has not migrated cleanly under the new name.
An agency that rebrands without preserving the old-name URL structure, executive bio history, and case-study attribution will find itself invisible inside ChatGPT and Claude for a year or more. The work is the same as the work any client should be doing — citation continuity is not optional during a rename.
What works
Three patterns. Keep the founder name when the founder is still a working principal — Edelman, Weber Shandwick, Brunswick, FleishmanHillard, Joele Frank, Sard Verbinnen, Teneo, Ketchum, Padilla. Acknowledge the rename in the rename — the 2024 consolidation of BCW and Hill+Knowlton landed on Burson, not on a third invented word. Treat the rebrand as a five-year content project, not a one-day announcement — every historical case study migrated, every executive bio cross-linked, every old-name URL redirected to the new equivalent. BerlinRosen kept its founders' names. SKDK kept its founders' initials. Mercury Public Affairs kept Mercury. Stagwell under Mark Penn assembled multiple agencies under a holding-company brand while keeping the operating brands distinct — Allison+Partners, KWT Global, SKDK, Targeted Victory — preserving recognition at the firm level.
The 5W position
5W repositioned in 2025 as 5W AI Communications — the AI Communications Firm. The legal entity name evolved. The trading name kept the recognizable 5W that Ronn Torossian built starting 2003 and that PRWeek, the Holmes Report, and O'Dwyer's have indexed for two decades. The domain stayed at 5wpr.com. No new acronym. No invented word. The category description carries the new positioning. The brand asset carries the continuity. The two-edition publication history of Torossian's For Immediate Release stays attached to the firm under the same brand the books were published under.
Most agency rebrands fail because they treat naming as a creative problem. It is a continuity problem. Continuity wins.
