The Living Room Has Become a Platform Battlefield

Ofcom’s Media Nations 2026 report, published on 29 July, contains a finding that deserves more attention than the familiar story of linear television decline: YouTube viewing on television sets has more than doubled since 2022.

The average person watched 19 minutes of YouTube a day on a TV set in 2025, up from nine minutes three years earlier. Across devices in the home, YouTube viewing reached 41 minutes a day. This is not simply a change in where audiences watch video. It changes who controls discovery, advertising inventory and the commercial terms of access to the largest screen in the home.

For years, the television set was principally a destination for broadcasters and, later, subscription streaming services. It is increasingly an interface through which platforms, device manufacturers, app stores and content owners compete to determine the next viewing choice.

The contest for television is increasingly decided before a programme has even begun.

The screen matters, but the interface matters more

There is a temptation to frame the shift as a straightforward contest between “traditional television” and online video. The evidence is less tidy. Broadcaster content still represented 53% of the average 4 hours and 27 minutes of daily in-home video viewing in 2025. Broadcaster on-demand viewing is growing, even as weekly reach for live and recorded television declines.

The significant development is convergence. YouTube is no longer confined to a phone or laptop; broadcaster apps are no longer merely catch-up services; subscription platforms are adding advertising; and television manufacturers are building their own content environments, often financed through targeted advertising. Each is competing for the same scarce commodity: the viewer’s willingness to choose, stay and return.

This makes the home screen a strategic asset. The order in which apps appear, the quality of search, the default recommendation rail and the friction involved in moving between services can shape viewing as surely as a commissioning budget. A good programme remains essential, but it may never receive consideration if it is poorly surfaced.

For marketers, this also weakens the usefulness of broad labels such as “TV”, “digital video” and “social”. The same television set can now deliver a broadcaster’s live sport, a subscription drama, creator-led video, a shoppable stream or an advertising-funded channel in the space of an evening. The screen is shared; the viewer’s mindset, commercial context and measurement framework are not.

A new problem for media planning

The commercial implication is not that every budget should follow YouTube on to the television set. It is that device, context and discovery route need to sit alongside reach and frequency in planning decisions.

A viewer choosing a long-form programme through a broadcaster’s service is not necessarily in the same state of mind as a viewer passively following an autoplay recommendation. Nor should an impression on a connected television be treated as inherently equivalent to any other impression delivered to a large screen. Household viewing can involve multiple people, while targeting may be inferred from a patchwork of account, device and behavioural signals.

The challenge becomes more acute as subscription growth slows. Ofcom reports that 70% of UK households had at least one subscription video-on-demand service in the first quarter of 2026, only two percentage points higher than in 2022. Revenue growth is therefore increasingly being supported by price rises, bundles and advertising. Platforms that once competed mostly for subscriptions are now also competing for advertiser demand.

That will place greater value on trusted measurement, clear brand-safety standards and an honest account of duplication. A campaign that appears to reach a large connected-TV audience may be repeatedly reaching the same households across several services. Conversely, a narrowly defined “television” plan can miss younger audiences whose living-room viewing begins with a platform rather than an electronic programme guide.

The right response is not to abandon established media categories overnight. It is to make them more precise. Planners should ask how people arrived at the content, whether the environment supports the intended brand association, how attention is likely to be distributed, and what can genuinely be measured rather than modelled.

Broadcasters have an asset that platforms cannot easily reproduce

The shift should not be mistaken for a verdict against broadcasters. Ofcom’s report records the continuing power of shared live moments: England’s World Cup quarter-final and semi-final drew peak audiences of 18 million and 24 million respectively across ITV and BBC platforms. Public service broadcasters also retain deep libraries of UK-originated programming and a strong association with trusted, high-quality content.

Their challenge is distributional as much as editorial. Broadcasters must protect the value of their brands and advertising environments while ensuring their content appears where audiences now begin their search. Partnerships with YouTube can extend reach, particularly among audiences who may not open a broadcaster app as a first choice. But reach bought through another platform comes with a trade-off: less direct control over data, recommendations, audience relationships and the rules of monetisation.

That trade-off needs active management. Full-length programming, clips, creator collaborations and platform-first formats may each have a role, but they should serve a clear portfolio strategy. Publishing everywhere without deciding what each channel is expected to achieve risks handing the most valuable audience relationship to the intermediary.

Interface design is becoming a market issue

Ofcom’s separate behavioural audit of online advertising services offers a useful wider lesson. It found that some platform journeys prioritised speed, ease and performance over verification, transparency and early risk mitigation. The research concerned fraudulent advertising, but the principle travels: commercial systems are shaped by the choices embedded in their interfaces.

As television becomes more platform-led, those choices will matter to brands, creators and audiences alike. Which services are prominent? How clearly are advertisements labelled? What reporting tools exist? Who can verify a buyer, a seller or an advertiser? And how much visibility do users have into why a particular recommendation appears?

These are no longer minor user-experience questions. They influence competition, trust and the distribution of advertising revenue.

For businesses, the immediate task is practical. Audit viewing and campaign data by service and device; distinguish reach from attention; scrutinise the route by which audiences find content; and avoid treating connected TV as a single, uniform channel. The living room is still a powerful media environment. It is simply becoming a more contested one.
