Consolidated TV viewing continued its seemingly relentless decline in 2018, falling 5% year-on-year (YOY)—its worst drop since the phenomenon began in 2011.

Meanwhile, unmatched TV set use—which includes Netflix, Amazon and YouTube consumption, as well as gaming—continued its upwards trajectory across all age groups, now accounting for 20% of total TV set time.

Consolidated TV viewing is increasingly reliant on its core viewers, with half of all viewing accounted for by the 20% of people who watch the most, up from two-fifths in 2010.

Our central case forecast with orderly EU withdrawal predicts 2.7% growth for total UK advertising spend, down from 4.7% in 2018. We have a no-deal Brexit scenario that predicts a smaller advertising recession than in 2009, with total ad spend declining 3% and display down 5.3% in 2019

The total advertising figures partly mask the pressure on UK consumers, through an expansion of the measured advertising spend universe. This is due to significant self-serve online advertising growth by SMEs, and non-advertising marketing budgets moving to online advertising platforms

In a downturn, we’d expect advertisers to become more tactical, which would disproportionally affect display media including TV, which is further affected by declining commercial impacts among younger adults. Search and social advertising would see only small growth through the first year of a recession
