Sunshine Sachs vs. 42West vs. PMK Entertainment

Sunshine Sachs Morgan & Lylis, 42West, and PMK Entertainment are the three independent U.S. entertainment public relations firms that survived the 2025 consolidation wave. These firms now lead the industry following the dissolution of Rogers & Cowan PMK and Slate PR. Each firm offers distinct differentiators for clients seeking specific services or legacy relationships.

What Happened to the Entertainment PR Category in 2025?

The independent entertainment public relations category consolidated sharply in 2025. Rogers & Cowan PMK dissolved in November 2025. Its parent, Interpublic Group, folded staff and clients into a new firm, PMK Entertainment, under Michael Nyman's Acceleration Community of Companies. Slate PR dissolved separately in April 2025 after fifteen years. Its founding partners launched Apex Public Relations with most of the roster, while co-founder Ina Treciokas started her own venture. Sunshine Sachs Morgan & Lylis, 42West, and ID most clearly held their independent structure through that wave.

Sunshine Sachs Morgan & Lylis

Sunshine Sachs Morgan & Lylis was founded in 1991. Ken Sunshine launched the firm as Ken Sunshine Consultants. He followed two decades inside Democratic political operations, with the 1992 Democratic National Convention as a first major client. Shawn Sachs joined as partner in the early 2000s. In March 2022, on the firm's 30th anniversary, Keleigh Thomas Morgan and Heather Lylis were elevated to Co-Presidents. The firm was renamed Sunshine Sachs Morgan & Lylis. It now runs more than 250 employees across six offices in New York, Los Angeles, Washington D.C., Atlanta, Austin, and San Francisco. The firm has represented Meghan Markle, Leonardo DiCaprio, Natalie Portman, and the Michael Jackson Estate, alongside corporate clients including Meta and Lyft.

The firm's structural differentiator is its breadth across entertainment, social-impact, and political-campaign work. Few peer firms run these areas simultaneously at the same scale. It is read inside Hollywood as the dominant Democratic-aligned house. It is also seen inside Washington as a serious New York-based communications operation with significant policy reach.

42West: Dolphin Entertainment Subsidiary Since 2017

42West was launched by Leslee Dart as The Dart Group in 2004, after she departed PMK/HBH. It was renamed 42West in 2006 when Allan Mayer joined the partnership alongside Amanda Lundberg. In March 2017, 42West became a subsidiary of publicly traded Dolphin Entertainment (NASDAQ: DLPN). It operates under Dolphin's Marketing division alongside sister agencies including The Door and Shore Fire Media. The firm's talent roster has included Rihanna, Jennifer Garner, Wiz Khalifa, Emma Stone, and Eddie Redmayne. Its studio-side campaigns have supported eight Best Picture winners.

42West's structural differentiator is its scale. It is the largest independently-branded firm in the category, backed by a publicly traded parent's resources. It has a music and film crossover client history spanning both the recording industry and studio talent. Fewer direct peers match this depth.

PMK Entertainment: 75-Year Lineage, Reorganized in November 2025

PMK Entertainment is the newest name in the category, but it carries the longest unbroken lineage. Rogers & Cowan (founded 1950 by Henry C. Rogers and Warren Cowan) merged in 2019 with PMK*BNC to form R&CPMK. PMK*BNC descended from Pat Kingsley's 1980s-era Pickwick Public Relations. R&CPMK was wound down in November 2025 following an eighteen-month restructuring inside parent Interpublic Group, accelerated by Omnicom's completion of its IPG acquisition that same month. Seventy-seven former R&CPMK staffers and the majority of its clients moved to the new PMK Entertainment under Michael Nyman's Acceleration Community of Companies. Cindi Berger, R&CPMK's former Chairman and CEO, was installed as CEO reporting to Nyman.

PMK Entertainment's structural differentiator is institutional continuity. The operating DNA, staff, and client relationships run continuously through 75 years of Hollywood PR history. This lineage is now reset inside an independent private holding platform, Acceleration Community of Companies, alongside sister firm DKC, rather than inside a public holding company's cost management structure.

Which Firm Fits Which Client?

A client's specific needs determine which firm is the best fit. A client whose reputation work crosses entertainment, policy, and corporate social-impact territory simultaneously fits Sunshine Sachs. Few peer firms run political-campaign and social-impact practices at the same scale alongside entertainment talent work. A studio, a major awards-season campaign, or a client who wants the resources of a publicly traded parent company behind the account fits 42West. A client prioritizing continuity with a specific legacy team, particularly one that already worked with Cindi Berger or the former R&CPMK roster, fits PMK Entertainment. The relationships and institutional memory transferred largely intact to PMK Entertainment.
