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.

For an unproven service to attract 1.3 million active users in its first five weeks is impressive. But by its own account, Quibi’s launch underwhelmed.

Sizeable subscriber targets—7 million by year one and 16 million by year three—justify a level of spend never seen in short-form video, but are ambitious for an experimental start-up with limited brand equity.

The service’s failure to recognise the social side of mobile media, restricted use case and, critically, lack of a hit show increased scepticism of product/market fit. Now Quibi must adapt the product with knowledge of user preferences and reassess its targets, provided it can afford to do so.

Amazon Channels’ aggregation of third-party streaming services enhances the consumer appeal of its wider video proposition, provides incremental revenues and increases the stickiness of the Prime shopping service

Content partners range from major players (e.g. Discovery and ITV) to the more niche (e.g. MUBI and Tastemade), who all benefit from a ready-made platform, billing relationships and a receptive subscriber base. But the revenue shares, data costs and lack of direct customer relationships remain too high a price for some

Two and a half years on from its UK launch, opportunities for live, ad-supported and bundled content are diversifying the platform, but Amazon must prioritise discovery within Prime Video to continue to flourish

With c.22m accounts across 44m devices, Roku has a US footprint which exceeds the largest pay-TV platforms

Limited competitive advantages highlight the scale of this achievement, but also leave the pioneering firm vulnerable to activities from bigger, wealthier rivals Apple, Amazon, and Google as well as pay-TV providers

The odds are stacked against Roku, but continuing the innovation in production and product that built its lead may secure future success

With the UK perhaps Netflix’s most valuable market outside the US—home to a stellar production sector—the streaming service is escalating its foray into local production, opening a content hub in London and moving from co-productions to direct commissions

As UK content completely dominates UK video viewing outside of the SVODs, to expand subscription reach Netflix is endeavouring to become an alternative to the PSBs’ entertainment output; this local spend is efficient given the universality and worldwide appetite for British content

With a growing proportion of local content expenditure now coming from Netflix and other SVODs, there are ramifications for both broadcasters and producers—loss of viewing, potential market pressure, increased competition for premium content and hesitancy around their own SVOD plans—along with implications for the cultural landscape
