There is no single “UK audience”. Media behaviour changes by age, platform, life stage and level of digital access, which means the best advertising channel depends on who a business is actually trying to reach. Ofcom’s 2025 data shows how wide those differences can be. Social media reaches 94% of people aged 15–24 each month, while use among people aged 75+ is much lower at 54%. At the same time, older audiences remain more dependent on traditional television, radio and print, and 20% of people aged 75+ had no home internet access. These figures explain why digital media attracts large budgets without proving that it should replace traditional media for every advertiser. The right starting point is not the channel. It is the audience.
Why younger audiences push advertisers toward digital channels
Younger people spend a large share of their media time online, and that changes where brands need to appear. Ofcom reports very high social-media use among younger adults, while platforms such as YouTube, Instagram and TikTok play a major role in entertainment, discovery and culture.
YouTube reaches 94% of UK adults overall, and TikTok reached 56% of online adults in May 2025, with especially strong use among younger adults. For brands targeting students, younger workers, entertainment audiences or trend-led categories, avoiding digital media can mean avoiding the places where the audience spends a large part of its time.
The advantage is relevance. Digital platforms allow advertisers to place messages inside environments already used frequently by younger audiences. Creative can also be adapted to fit the platform rather than simply copying a television or print advert into a smaller space.
The disadvantage is competition. Younger users see enormous volumes of content and advertising. Brands must compete not only with other advertisers but with creators, friends, entertainment and news. High platform use therefore creates opportunity and clutter at the same time.
There is also a danger in overgeneralising. Not every young person uses the same platform, and usage patterns change quickly. A campaign built around last year’s assumptions can become outdated surprisingly fast.
Why older audiences keep traditional media commercially important
Older audiences are increasingly online, but digital adoption is not complete. Ofcom reports that 13% of people aged 65+ and 20% of those aged 75+ had no home internet access in 2025. Even among connected older users, traditional media tends to remain more important than it is among younger groups.
This creates a strong case for maintaining television, radio and print in sectors where older customers matter. Retirement services, healthcare, mobility products, local services and some financial products may lose meaningful reach if advertising moves entirely online.
The advantage of traditional media is accessibility and familiarity. Broadcast and print do not require the same level of digital literacy, account use or device confidence. They can also reach people in routines that remain stable, such as listening to radio during the day or watching scheduled television.
The disadvantage is targeting precision. A television or radio campaign may reach many people outside the intended segment. That can increase waste compared with a narrowly targeted digital campaign.
Older audiences are also not one homogeneous group. A 60-year-old smartphone user and an 85-year-old with limited internet access may have completely different media habits. Age is useful as a planning signal, but it should never become a lazy stereotype.
Digital targeting improves precision but creates new risks
One of digital media’s strongest advantages is segmentation. Advertisers can target by age, geography, interests, search behaviour, website activity and first-party customer data. This can make campaigns more relevant and reduce the number of impressions shown to people unlikely to respond.
For example, a company selling software to small businesses can focus on professional audiences rather than buying broad national reach. A retailer can show different product messages to different customer groups. A local service company can limit ads to the areas it actually serves.
The benefit is efficiency. The drawback is that targeting can become too narrow. When campaigns are divided into many small segments, the brand can lose scale and consistency. Different audiences may see entirely different messages, making it harder to build one clear identity.
There are also privacy concerns. Behavioural targeting relies on data, inferred interests and user signals. Regulation and consumer expectations increasingly limit how far advertisers can go. A targeting method that appears technically possible may still be commercially unwise if customers see it as intrusive.
Segmentation can also encourage stereotyping. People are more complex than demographic labels. Assuming that every older person dislikes digital media or every younger person ignores television can produce bad planning decisions. The most useful audience strategy combines demographic data with actual behaviour.
Platform choice matters just as much as the digital-versus-traditional choice
Digital media is not one audience. Different platforms attract different user profiles and support different kinds of behaviour. Ofcom data shows that Facebook and Messenger are relatively more weighted toward users aged 35+, while Instagram, YouTube and TikTok skew younger.
This means a campaign described simply as “social media” is not a complete strategy. A brand may perform well on Facebook and poorly on TikTok, or vice versa, because the audience, content style and user expectations differ.
The advantage of digital diversity is choice. Advertisers can select platforms that align with the audience and campaign objective. Search can capture intent. YouTube can provide long-form or short-form video. Social platforms can build awareness, community or response.
The disadvantage is fragmentation. Each platform has different formats, algorithms, measurement systems and creative requirements. Managing several channels can increase production cost and make cross-platform frequency difficult to control.
Traditional media has a similar internal diversity. Television, radio, print and outdoor serve different audiences and contexts. A broad label such as “traditional” can hide important differences just as much as the word “digital” does.
The useful planning principle is therefore to compare specific channels and audiences rather than treating digital and traditional media as two simple blocks.
How advertisers should choose the media mix around the audience
The strongest media strategy begins with a clear description of the people the business needs to influence. That means understanding age, location, purchase behaviour, digital access, media habits and the stage of the customer journey.
If the audience is young, highly connected and comfortable with online video and social platforms, digital media will usually play a major role. If the audience includes older or less digitally connected groups, traditional channels can remain essential. For broad consumer brands, a combination may be more effective than choosing one side.
The advantage of digital media is precision, speed and personalisation. The disadvantage is fragmentation, privacy complexity and the risk of over-targeting. The advantage of traditional media is broad reach, shared context and accessibility. The disadvantage is waste and lower granularity.
A balanced plan gives each medium a specific job. Television might create broad awareness. Radio might provide repeated local exposure. Search may capture people actively looking for a solution. Social media may reach younger audiences or support ongoing engagement. Outdoor may reinforce visibility in a particular location.
The wrong approach is to choose media because one channel is fashionable or because industry spend is moving in a particular direction. Market trends matter, but audience behaviour matters more. A platform with enormous national reach is useless if the intended customer is not there, while a smaller traditional channel can be valuable if it reaches the right group repeatedly and credibly.
The best conclusion is therefore simple: start with the audience, then choose the medium. Digital advertising has grown because audiences are increasingly online and because targeting is powerful. Traditional media still matters because not every audience behaves the same way and because broad shared exposure can still create value. The winning channel is not the newest one or the oldest one. It is the one that reaches the intended people in a context where the message has a realistic chance of being noticed, understood and remembered.
