Agencies Warn AI-created Briefs Causing Bloat
Agency leaders are increasingly concerned that the overuse of AI tools to write advertising and media briefs is undermining productivity and staff well-being. At Digiday's Media Buying Summit, M&C Saatchi's North American CEO Nadja Bellan-White estimated that 85% of client briefs are now AI-generated, leading to excessively long documents filled with jargon but lacking strategic vision. A Basis Technologies survey found that 56.4% of marketers and agencies use AI for brief creation. Executives report that some briefs are disjointed, lack a clear marketing goal, and reflect a decline in critical thinking. The article highlights 'cognitive offloading' and cites a 2025 MIT study showing reduced brain activity when using AI assistance. Some leaders suggest managers should intervene to reduce reliance on AI, even recommending unplugging laptops and having face-to-face conversations.

AI's Dual Impact on Agency Staff: Efficiency and Pressure
The article examines how AI is reshaping agency operations, highlighting increased efficiency alongside heightened pressure on staff. WPP plans to cut 1,000 more jobs by end of 2026, adding to 11,000 cuts since early 2025, as part of a strategic shift toward a leaner, AI-enabled business. Other holding companies like Havas have automated processes, with CEO Yannick Bolloré noting they've automated everything possible. A Basis report reveals 70% of agency professionals find their jobs harder than two years ago, and 54% report strained client relationships due to higher expectations and compressed timelines. Anonymous senior agency sources confirm the pressure to 'do more with less' but note morale varies. While AI saves time, especially with agentic AI for client queries, concerns remain about job security, tool proliferation, and the risk of over-reliance on AI for tasks like email writing. The article suggests agencies are adapting, but not without friction.
Agencies Reimagine Staffing Amid Workplace AI Tensions
Agencies are adopting AI agents but haven't restructured teams or career paths. The article highlights tensions from AI use, with staff skipping critical thinking. Agencies like Monks and M&C Saatchi are implementing training programs. Monks is strategically hiring for junior roles, shifting tasks away from mundane spreadsheet work. Some roles have limited access to powerful AI models to control costs. The article cites a Digiday survey showing 9% of agencies are not pursuing agentic AI. Apollo Partners data indicates AI gains have not improved margins outside tech. The future may include roles like 'AI checkers' to ensure AI output quality. The article is from Digiday's Media Buying Summit coverage.
