This linear TV advertising UK guide explains how scheduled broadcast airtime can help advertisers plan reach, cost and campaign delivery before money is committed.
What counts as linear TV
Linear TV means scheduled broadcast channels watched live or near-live: BBC One, ITV1, Channel 4, Channel 5, Sky channels, UKTV, regional channels and multichannel stations on Freeview, Sky, Virgin Media, Freesat and similar platforms. It is different from BVOD/CTV, where the viewer chooses streamed content through ITVX, Channel 4, 5, Sky Go, NOW, YouTube, Netflix, Prime Video and so on.
Market position
Ofcom’s latest Media Nations report says growth in broadcaster online video has not fully offset the decline in linear TV viewing, but broadcaster content still accounts for the majority of in-home viewing. So the direction of travel is clear: audiences are moving to streaming, but broadcasters remain central to UK viewing.
Audience pattern
Linear TV skews older than streaming and is weakest among younger viewers. Under-35s are much more likely to start with YouTube, Netflix, TikTok, Prime Video or Disney+ than a scheduled channel. However, linear still performs well for shared household viewing, live sport, major entertainment, news, soaps, big reality formats and national moments.
Advertising role
For advertisers, linear TV still offers:
- Fast national reach
- High attention on the main TV screen
- Trusted, regulated environments
- Strong brand-building effects
- Broad demographic delivery
- Powerful context around live and premium programming
Thinkbox says commercial TV and BVOD together reach 85% of adults each week, which shows why TV remains a scale medium even as viewing fragments.
Planning a linear TV campaign
If you are planning a linear TV campaign, it is worth understanding how airtime costs are calculated before committing spend. See TV Advertising Costs UK.
Linear TV can also work alongside BVOD and connected TV when those channels have a clear role in the plan.
