UK TV advertising planning and media buying

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.

What the evidence says TV returns

The most robust UK dataset on this is Profit Ability 2, run for Thinkbox by Ebiquity, EssenceMediacom, Gain Theory, Mindshare and Wavemaker UK. It modelled 141 brands, £1.8bn of media spend, 10 channels and 14 sectors, 2021-2023 data.

£4.11profit per £1 once sustained effects are counted (all media)

Linear TV and BVOD together accounted for 54.7% of all advertising-generated profit in the study, with linear TV alone at 46.6%.

Your own return depends on category, creative, budget and how well the campaign is planned - which is exactly why it is worth modelling before you commit rather than after.

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:

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.
