In the UK, carriage on Sky Q will give the new service the opportunity to prove its worth to viewers. Without integration with the UK's biggest pay-TV platform, growing scale is difficult for nascent DTC services.

Elsewhere in Europe, Discovery seeks to bundle too. Unlike the US, where the company has a single model—basic cable—in Europe it operates both free-to-air and pay channels, and it also owns Eurosport.

Ultimate success will come down to whether Discovery's "real life content" is essential and defensible. Generally there is little evidence of people taking services that are not broad, while the barriers to entry for competitors wishing to commission "real life content" are lower than other genres.

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.

In response to COVID-19 and the associated lockdown and economic crash, advertisers have slashed budgets. Online budgets are not immune.

This has clarified features of the online ad market: it is demand-driven, relies heavily on SMEs and startups, and is built on direct response campaigns.

We expect online advertising to outperform other media, and for platforms to further gain share. But with a very few exceptions, this health and economic disaster is good for nobody.

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.
