In this report, we examine the completion rates of every scripted series since 2018 across all the major UK broadcast channels.

Comparing scripted programmes across different channels by overall viewing is difficult as these numbers are affected by promotion, prominence, competition, the quality of online player UIs and availability.

The rate that series are completed—viewing of the final episode as a proportion of the first episode—eliminates these and allows comparison.

COVID-19 has led to an unprecedented decline in advertiser demand for TV, and while the steepest drop has occurred, broadcasters will feel the impact over a long period of time.

Programming costs are being cut or deferred, but it is not possible—or even sensible—to reduce total programming budgets significantly in the mid-term due to existing contractual commitments.

Increased government support in the form of advertising spend, a loosening of Channel 4's programming obligations—the lifeblood of the independent production sector—and revisions to existing measures (to capture a greater proportion of freelancers) will be required to ensure a flourishing, vibrant sector for the future.

Linear TV is still a mass market medium, watched by 90% of the UK population each week. However, our latest viewing forecasts predict broadcasters will account for two-thirds of all video viewing in 2028, down from c. 80% today, due to the relentless rise of online video services.

Total viewing will continue to increase as more short-form content is squeezed into people’s days, particularly on portable devices, but the key battleground for eyeballs will remain the TV screen.

The online shift has already had a huge impact among younger age groups, with only 55% of under-35s’ current viewing to broadcasters. Older audiences are slowly starting to follow suit, but have a long way to go.
