Digital Content Next has filed new data in its copyright litigation against OpenAI and Microsoft, showing a significant decline in publisher traffic and revenue. The filing links these drops to AI search tools and generative AI models that summarize original content.
Why it matters
The evidence suggests a systemic erosion of the traditional web traffic model as search engines shift toward AI-generated answers. This trend threatens the long-term viability of content-driven advertising and subscription models.
A study by Carnegie Mellon University and the Indian School of Business measured that Google AI Overviews reduce outbound organic clicks by 39.8%. Meanwhile, surveyed publisher sites saw total page views drop 18% between 2023 and 2025.
The players
Digital Content Next
A trade association representing major digital media companies that produces research on publishing metrics and advocates for publisher rights.
OpenAI
An AI research and deployment company that produces the ChatGPT service and large language models used in search-driven summaries.
Microsoft
A global technology company that integrates generative AI models into its Bing search engine and maintains a strategic partnership with OpenAI.
The primary search engine operator that introduced AI Overviews and currently faces scrutiny for declining referral traffic.
The details
Tech companies employ retrieval-augmented generation (RAG) — a process where models retrieve external data to inform responses — to scrape and summarize publisher articles. These tools effectively answer user queries within the search interface, preventing users from clicking through to the original source. This process has led to a 11% decrease in total minutes spent on publisher websites from 2023 to 2025.
Timeline
November 2023: ChatGPT launched.
2023-2025: Unique visitors to publisher websites fell by 26%.
May 2024: Google began rolling out AI summaries.
2025: Advertising and total revenue for surveyed members fell 5%.
May and June 2026: Referral traffic from Google search fell 22%.
The Tech Race
The filing adds quantitative weight to the ongoing copyright litigation against OpenAI and Microsoft. It highlights a critical departure from historical search patterns where traffic growth was inherently tied to search engine usage.
Readers may find that the information they previously accessed by visiting news websites is increasingly presented within search interfaces. This shift directly impacts the sustainability of publishers that rely on advertising for 84% of their revenue.
The takeaway
The sustained drop in referral traffic indicates that publishers face an urgent challenge as AI tools capture user attention. Industry observers should watch for potential legal or licensing resolutions in the ongoing litigation that could establish new frameworks for content compensation.
