Advertising income has been the lifeblood of commercial TV for decades, but declining linear audiences—combined with digital video alternatives—mean the TV advertising model must evolve to ensure it remains as potent a medium for brands as ever.

Lack of effective audience measurement and somewhat opaque advertiser/agency/sales house relationships are hampering linear TV advertising revenues. Both issues need resolving to underpin a healthier ecosystem overall.

Flexibility is key to this evolution. A move to audience buys across most linear and BVOD inventory would provide greater flexibility and targeting for advertisers, and would sit alongside some premium context buys. A greater onus on volume deals would give broadcasters more certainty to invest in content and their advertising propositions.

Online advertising became the majority of all UK ad spend last year, in step with China but ahead of all other major markets. 

Direct response has further increased its share to 54% of UK ad spend, fuelled by the self-serve platforms of Google, Facebook and Amazon, while content media nets just 11% of the online advertising pot.

We estimate that all online-delivered channels - including "pure play" online properties, broadcaster VOD, digital out-of-home and online radio - could account for well over 60% of UK ad spend by 2020, but only with improved commitment to industry governance.
