British newspapers and magazines now take three pounds in every hundred spent on advertising here.

The Advertising Association and WARC publish the definitive account of what Britain spends on advertising, and in April they published a table for 2025 with the channels broken out.

The total was 46,682.7 million pounds. Search took 17,876.1 million of it. Social media took 11,515.4 million. Retail media took 3,749.9 million. Television took 5,216.1 million. Published media, meaning every national newspaper, regional newspaper and magazine brand in the country, print and online together, took 1,552.2 million.

Those are the channels. The interesting part is who owns each of them, and which way each one is moving.

Two shares follow from that table, and the arithmetic is this desk's rather than theirs. Search and social media together were 63.0 per cent of UK advertising investment. Published media was 3.3 per cent.

The direction matters more than the level. In 2025 social media grew 21.0 per cent, retail media 17.5 per cent, addressable television 37.0 per cent and search 5.8 per cent. Published media fell 5.1 per cent, with regional news brands down 6.0 per cent. Other online display, which is the open web outside the big platforms, fell 20.0 per cent and is forecast to fall a further 19.7 per cent this year and 35.0 per cent next.

The Q1 2026 report, published on 30 July, points the same way. Total investment up 9.3 per cent. Published media down 5.9 per cent, regional news brands down 9.7 per cent, other online display down 10.7 per cent.

So Britain has a growing advertising market and a shrinking British-owned media sector inside it, at the same time.

Here is where the evidence stops and the read begins.

A country can have both of those things because a growing share of an advertising market is not the purchase of a page or a slot from a domestic publisher. It is the purchase of access to a system that was built, priced and operated somewhere else. What the country retains from that transaction is the buying rather than the building. That is not a complaint about the platforms, whose products work, and it is not a claim that money is leaving the country, because it plainly is not: 46.7 billion pounds was spent here and much of it paid British planners, British sales teams and British production.

The narrower point is about what a national capability is made of. An industry that owns its own inventory has bargaining power, a training ladder and a reason to keep skilled people. An industry that resells someone else's has margin.

Two cautions, both of which cut against the neat version.

Retail media should not be lumped in with the platforms. Much of it is British grocers and retailers selling advertising on their own sites, which is domestic inventory by any definition, and it grew 17.5 per cent.

And Amazon, Google and Meta are not interchangeable with the whole of search and social. Social media as measured here includes YouTube and TikTok, and the ownership map is more mixed than a headline allows.

One absence is worth recording, because absence is a claim and this one is sourced. Asked in its own published notes when it will begin measuring spending on generative AI advertising, the Advertising Association says it is exploring the question and not committing at this stage. The definitive record of UK advertising expenditure does not yet have a line for the technology the industry says is reshaping the work.

A last figure, and this desk is telling you exactly how much weight it will bear. Indeed's mid-year update, reported in the UK trade press on 3 August, has UK job postings 32 per cent below their February 2020 baseline while the euro area sits 5 per cent above its own and the United States 2 per cent above. This desk has not been able to open the publisher's page, only reports of it that agree with each other, so the figure is recorded as corroborated rather than confirmed and is not carrying anything here. It is offered because it is the only comparison of its kind available this week, and because a British reader is entitled to know that the country's hiring weakness is not a shared European condition.

The census that runs beneath all of this counts 24,963 people. That is the workforce making the advertising that 46.7 billion pounds buys, and it is 6.8 per cent smaller than it was a year ago.
