Agencies, Tech Providers, and the Open Web's Decline
An AdExchanger roundup examines how agency–tech relationships and shifting media-buying patterns are reshaping the open web. Agencies can implicitly lock brands into specific technology stacks or receive subsidized labor from tech vendors, a consultant says. Publicis recently won Microsoft’s media account and has named Microsoft Azure its preferred cloud while giving employees access to Copilot. WPP’s CFO said holding companies are dialing back the open internet as a primary buying channel, reallocating spend toward platforms like Meta, Amazon and streaming where data and measurement are more tightly controlled. The piece also reports The CW’s new streaming distribution deals — ESPN will have exclusive streaming rights to roughly 800 hours of CW sports annually, and The CW will put about 800 hours of entertainment content on The Roku Channel — and notes several shorter industry items including a Hightouch Series D raise and Roku’s new SVOD milestone.
Highlights structural shifts in media buying — agencies tied to tech vendors and holding companies reducing open-web spend toward walled gardens and streaming — which affects programmatic demand, DSP/SSP roles and publisher monetization.

Media Buyers Eye Organic Strategies Amid Budget Shifts
The AdExchanger roundup covers three ad‑industry threads: creative lessons from ‘viral app’ growth tactics, agency backlash against The Trade Desk’s OpenPath, and growing infrastructure risks tied to AI. Marcus Burke of ctrl shift argues mobile media buyers should adopt organic-virality techniques — simplified onboarding, gamified prompts and early review asks — to improve conversions. Several holdco agencies, including Dentsu and WPP, are shifting budgets away from The Trade Desk’s OpenPath over transparency and perceived hidden-fee concerns; The Trade Desk says OpenPath fees are roughly 4% of spend. The piece also links rising major outages to infrastructure consolidation (e.g., Cloudflare) and to incidents involving AI tooling — Amazon Web Services experienced AI-related outages involving an agentic coding assistant called Kiro. Short briefs note Anthropic’s new bug‑finding tool, NBCUniversal’s Peacock bundling plans, and a Finji complaint about TikTok‑modified ads.
SPUR launches AI content tracking standard, invites OpenAI, Google to board
A coalition of media organizations including the Guardian, Financial Times, BBC, Sky, and the AP has released a new standard for tracking how AI tools use publishers' content. The Standards for Publisher Usage Rights (SPUR) initiative published its content telemetry standard on October 2, 2026. The standard creates a process to track and report when content is retrieved, grounded, cited, presented, and engaged with by AI tools, and report usage back to publishers. SPUR has invited OpenAI, Anthropic, Google, Meta, and Microsoft to join its new AI Licensing Advisory Board to help shape implementation. The board aims to ensure tracking rules work for both publishers and AI companies. SPUR is also developing agent tooling for AI companies to adopt the standard, supporting transparent reporting and licensing. Pilot programs with tech and AI companies are planned.
