Commissioning in the Dark: How British Broadcasters Are Flying Blind on Streaming Data

There is a phrase that circulates with quiet frequency in the corridors of British broadcasting: we have the data. It is offered as reassurance — to talent, to independent producers, to anxious executives — that commissioning decisions are grounded in something more rigorous than instinct. But when pressed on what that data actually reveals, and how it shapes what gets made, the answers grow considerably less certain.

An investigation by Televisual into the streaming analytics practices of British broadcasters suggests that the gap between claimed capability and operational reality is wider than the industry publicly acknowledges. Several commissioning editors, speaking on condition of anonymity, described environments in which rich viewing data exists in principle but remains poorly integrated into the decisions that determine what appears on screen.

What the Numbers Actually Say — and Who Gets to See Them

The major British streaming platforms — BBC iPlayer, ITVX, Channel 4 streaming, and Channel 5's My5 — each collect substantial volumes of audience behaviour data. Play rates, completion percentages, drop-off points, search behaviour, device usage: the technical infrastructure for understanding audience engagement is, by any measure, sophisticated.

The problem, according to multiple industry sources, is not the collection of data but its interpretation, distribution, and ultimately its authority within commissioning conversations.

"There's a difference between having numbers and having understanding," said one senior figure at a mid-tier independent production company with long-standing relationships across several British broadcasters. "We'll get a report that tells us a show was watched by X million people in its first thirty days. But what that doesn't tell us is who stopped watching after episode two, or why certain demographics never started at all. And when we ask those questions, the answers are often vague."

This opacity is not uniform across the industry. The BBC, by virtue of its public accountability obligations, has invested considerably in audience research infrastructure, though even here, iPlayer analytics and traditional broadcast measurement have not always been fully reconciled. ITV's investment in ITVX has brought more granular first-party data into its commissioning process, though insiders suggest the cultural shift required to act on that data has been slower than the technical build.

The Inherited Assumption Problem

Perhaps more revealing than gaps in data collection is the persistence of what several sources described as inherited assumptions — beliefs about audience behaviour that predate the streaming era but continue to shape commissioning logic.

The notion that British audiences will reliably return to drama on a weeknight, that certain talent guarantees a built-in audience, or that a successful format in linear broadcasting will translate predictably to on-demand — these assumptions have not disappeared simply because the viewing environment has fundamentally changed.

"There's a commissioning editor at one major broadcaster who will greenlight almost anything with a particular presenter attached, based on that presenter's linear ratings from five years ago," said one development executive. "Nobody has seriously interrogated whether that relationship holds on streaming. The data might well support it — but nobody has looked."

This is not a trivial observation. When commissioning decisions are made on the basis of untested assumptions rather than current behavioural data, the consequences extend beyond individual commissions. Budgets are allocated, talent relationships are prioritised, and editorial strategies are constructed on foundations that may be structurally unsound.

The Transparency Deficit

One of the most persistent frustrations for independent producers is the asymmetry of information that characterises their relationships with broadcasters. When a production company delivers a series to a streaming platform, it typically receives limited access to performance data — often a single headline figure, delivered weeks after transmission, with little contextual detail.

This matters because it prevents producers from developing their own understanding of what is working. It also means that conversations about renewals, follow-up commissions, and format development are conducted almost entirely on the broadcaster's terms, with the producer unable to challenge or interrogate the numbers being cited.

"We made a six-part series for a major streaming platform and were told it had performed well," recounted one independent producer. "When we asked for specifics to help us develop the follow-up series, we were given a completion rate figure and told that was commercially sensitive. How do you develop a second series on that basis?"

The contrast with the United States is instructive. While American streamers — Netflix chief among them — have historically been even more secretive about raw viewership figures, there is a growing movement, partly driven by writers' and actors' guild pressure, towards greater transparency. In Britain, no equivalent advocacy has yet emerged with sufficient force.

Is Genuine Reform Possible?

There are reasons to be cautiously optimistic. The consolidation of streaming and linear measurement under BARB's expanded remit represents a meaningful step towards a more coherent picture of British viewing behaviour. ITVX's ongoing development of its first-party data capabilities suggests at least one major commercial broadcaster is serious about building commissioning intelligence on more rigorous foundations.

But structural reform requires more than better dashboards. It requires a commissioning culture willing to be challenged by what the data reveals — including the possibility that certain established assumptions, and certain established relationships, do not survive scrutiny.

For now, the data exists. What remains in question is whether British broadcasters are genuinely prepared to be guided by it — or whether the numbers will continue to serve primarily as post-hoc justification for decisions made on rather older grounds.
