Overton Catcher

Week of 29 August – 4 September 2026

1,364 stories across four markets, 30,467 articles.

On this page

Between 29 August and 4 September 2026 this project collected 30,467 articles and grouped them into 1,364 stories across four markets. A story is a cluster of articles close enough in meaning to be the same event3; independence is counted in owners, not outlets4. Superscripts link into the method page, where each measurement is defined once.

Volume

Counts are after duplicate feed entries are merged2, and they are not flat across the week: a weekend day runs about half a weekday1.

What the week was about

Stories ranked by the number of owners carrying them
The ranking is by owners, not by article count: what matters is how widely a story travelled, not how much was written.

The three widest stories in each market, with the words that separate each from the rest of its week6:

us-national. JD Vance Says He Wouldn’t Call Iran Conflict a War — 23 owners, 40 articles, published over 11 hours (Fox, Vance, Bartiromo, Maria). Key things to know about Lindsay Clancy's case after judge declares mistrial — 21 owners, 102 articles, published over 23 hours (Clancy, Lindsay, mistrial, trial). U.S. Strikes Iran in First Military Action in a Month — 21 owners, 71 articles, published over 23 hours (Iran, Island, Iranian, strikes).

uk-national. Keir Starmer’s resignation statement in full as he stands down as MP — 12 owners, 50 articles, published over 21 hours (Keir, Starmer, prime, Commons). Zack Polanski announces he will stand in Holborn and St Pancras by-election — 12 owners, 18 articles, published over 12 hours (Polanski, Zack, Holborn, Pancras). Reform UK conference LIVE: Nigel Farage to deliver speech as two key party figures step down over 'foreign donations' claim — 11 owners, 55 articles, published over 22 hours (Reform, Farage, Nigel, party).

uk-regional. Aigburth Road closed after woman hit by car - live updates — 5 owners, 23 articles, published over 19 hours (closed, collision, traffic, emergency). Seven arrested over death of newborn baby girl in Sheffield - everything known so far — 5 owners, 22 articles, published over 20 hours (murder, baby, newborn, girl). Keir Starmer to resign as MP as he confirms what he will do next — 5 owners, 22 articles, published over 17 hours (Keir, Starmer, Prime, Commons).

intl-state. Ukrainian lawmaker says Russian drone struck planes at Kyiv airport ahead of US envoys' visit — 9 owners, 54 articles, published over 19 hours (Witkoff, Kushner, Kyiv, envoys). 27 killed, over 40 injured in Russian drone strike on warehouse near Kyiv, says Ukraine — 9 owners, 44 articles, published over 20 hours (Kyiv, Russian, district, attack). Putin, Modi highlight expanding Russia-India ties, economic cooperation — 9 owners, 44 articles, published over 21 hours (Putin, summit, Modi, Kyrgyzstan).

The same day in four markets

Stories are clustered inside a market and never across them7. The boundary is worth reading on its own, because most of what a market carries never crosses it.

MarketStoriesAlso carried in another market
us-national49727%
uk-national27754%
uk-regional35030%
intl-state24046%

The match behind that last column is deliberately loose8: the claim being made is “nobody else ran this”, so it should fail towards saying a story travelled. At the strict threshold the same shares are 19%, 41%, 24% and 34%, in the order above.

Where an event did cross, the wording is the interesting part. The same day, the same event, as each market ran it:

How far stories travel

Distribution of owners per story
Most stories stop at three or four owners. The tail to the right is what a week actually shares.

Owner counts here are corrected for wire copy: two owners running one agency text under two mastheads count once between them5.

How long a story lasts

Owners carrying each long-running story, day by day
One panel per story that ran more than a single day. The line is how many owners carried it that day, so the shape says whether it spread, held, or faded.

A week-long story is a chain of daily clusters rather than one object10. Ordering is by how much of this week a story occupied, and it has to hold at least 3 days of it to appear11. The column worth reading is the last one: a story that opens wide was already everyone’s on day one, and one that opens narrow had to travel first12.

Each owner’s first, middle and last article in one story
The week’s largest story, one row per owner, ordered by when that owner first published. The dot sits on that owner’s first article and its area is how many they ran; the line runs on to their last. The bars along the top are how many articles ran in each 6-hour window.

Counting owners per day says how wide a story got; the rows above say how it filled up13. It is one story, though, not a claim about how these owners behave14.

Who moves together

Owner pairs ranked by excess co-occurrence
Measured against a null model that keeps both the size of each story and the output of each owner, so neither big news nor a prolific outlet can produce a score on its own. Computed over the whole archive, not just this week: the signal is longitudinal and a single week is too noisy to read.

A high score means two owners run the same stories more often than their volumes explain, which is not the same as coordination15. What it cannot say is whether either is following the other; for that the next section uses the clock.

How stories move between newsrooms

Owner pairs that publish closer together than the story explains
Inside every story each pair of owners is ranked by how close together the two published, measured against all the other pairs in that same story. Scoring against the story itself is what keeps big news out of the result: an event everybody reaches within the hour makes every pair look fast, and only a pair that is fast relative to its own story survives.

Direction is what separates the mechanisms, and it is the part a co-occurrence count cannot see16.

Measured over the whole archive rather than this week, and only after two controls: each owner’s own speed is subtracted, and the pair’s tightest quarter of stories is dropped17.

The same measurement can be asked of a single owner: is it upstream of the newsrooms it shares stories with, or downstream of them18?

The two ends read differently, and neither is an accusation19.

What the headline said first

Every version of an article’s text is kept, so a headline that changes after publication is visible. This week 1,985 headlines were rewritten, 940 of them substantially — less than half the words survived — and the median rewrite landed 4.3 hours after the article first appeared. Not all of that is a newsroom changing its mind20: requiring the two versions to be recognisably the same sentence, changed within a day, leaves 703 — and those are the ones below.

This is the one place in the corpus where an editorial decision is observed twice — the same newsroom, the same story, two framings hours apart21.

  • Warner Bros — “US strikes Iranian rocket launchers, official says, marking first attack in a month” → “US and Iran trade attacks, marking first major military escalation in a month”
  • Warner Bros — “What the jury in Lindsay Clancy’s trial is deliberating” → “Judge urges jury in Lindsay Clancy murder trial to ‘stay the course’ as it enters Day 4 of deliberations”
  • Warner Bros — “USPS whistleblower says system for Trump mail ballot rules could fail at multiple points” → “USPS whistleblower describes new plans for voting by mail hidden from the public”
  • News Corp — “U.S. Targets Iran in Fresh Wave of Strikes” → “U.S. and Iran Trade Strikes in Latest Fight for Control of Hormuz”
  • Disney — “Massachusetts Sen. Ed Markey faces younger, more moderate primary challenger” → “Mass. Sen. Ed Markey will defeat Rep. Seth Moulton in Democratic primary, AP projects”
  • Global — “Doctor colleague of child serial killer Lucy Letby named” → “Lucy Letby's consultant doctor 'boyfriend' named, two months after being found dead in car”

The examples are drawn from stories that at least 4 owners carried, not from the largest rewrites22.

Rewriting is not evenly spread. Emerson Collective changed the headline on 36% of what it published this week; across the owners with enough output to measure the rate runs from that down to a percent or two23.

What the rewrites do not show is a softening of language. Quotation marks appear in 116 rewritten headlines and disappear from 94; words that hold a claim at arm’s length — so-called, alleged, reportedly — move in 16 and out of 15. At that size neither is a finding. Distancing is thin enough in headlines that it has to be measured across the whole corpus rather than inside its edits, which is the next section.

Words that have to be quoted

This project is named after the Overton window, and everything above measures something else: the shape of distribution. The window is answered by how a word is marked, not by how far it travels24.

How often each term appears inside quotation marks
Counted over headlines and summaries in all four markets this week. A quoted term is one the outlet did not say in its own voice: either it flagged the word itself, or the word arrived inside someone else’s sentence.
TermMentionsIn quotation marksShare
genocide471634%
woke581933%

illegal264197%
election458163%
inflation15443%
migrant11722%
police1,611211%
far-right12211%

The separation is an order of magnitude and it is not subtle. Nothing about the count knows which words are contested — the list is fixed in advance, and it has to be25. Read the shares as a level, not as a movement26: the window is the change in them over months.

Method

Every measurement above is defined once, on the method page — the superscripts throughout this report link straight into it. Reports are generated without human editing and without a language model27.
