For much of the past eight years, Channel 4, the British free-to-air public broadcaster, has felt louder than ever. More confrontational. More willing to step into contested territory. More determined to provoke a reaction rather than quietly earn one.
Behind that noise, a quieter and more complicated conversation has been playing out among the people who actually make its programs.
That tension defines Ian Katz’s tenure more than any single commission.
When Katz arrived in 2017, he was not the obvious candidate. His background was in journalism, not television production. He had edited Newsnight, not built formats or sustained returning series. He brought a sharp instinct for narrative and public debate. What he did not bring was a track record of delivering repeatable hits at scale.
That distinction shaped both his strengths and his limitations.
Inside Channel 4, Katz pushed hard on what the broadcaster should say. The slate leaned into difficult subjects, from dramas like It’s a Sin, to fast-moving stories designed to land in the middle of national conversations, including investigations such as Russell Brand: In Plain Sight. When it worked, it reaffirmed Channel 4’s founding purpose as a public service broadcaster willing to challenge and unsettle.
Producers noticed.
“He backed things others wouldn’t touch,” one long-time supplier told me. “You always felt there was permission to go further.”
But that same producer added:
“Sometimes it felt like the conversation mattered more than whether anyone was actually watching.”
That tension runs through much of the feedback.
For all the clarity around tone, Channel 4 became harder to read as a buyer. Priorities shifted as the organization accelerated its move toward streaming. Some producers thrived. Others struggled to navigate.
“It became less predictable,” one executive said. “Which is exciting creatively, but commercially it can be difficult to build a business around.”
Katz’s Channel 4 made programs people talked about. It commissioned distinctive factual series such as To Catch a Copper and The Jury: Murder Trial, alongside investigations including Russell Brand: In Plain Sight. It backed sitcoms like Big Boys, widely praised for its voice and emotional precision. It also presided over returning successes including Gogglebox, The Great British Bake Off and Taskmaster.
What it found more intermittently was scale.
The music competition show The Piano stands as the clearest example of a Katz-era format that travelled both emotionally and commercially. But it was the exception.
The familiar critique is that Katz failed to deliver defining hits. The more uncomfortable question is whether those hits are meaningfully easier to identify anywhere else.
Across the industry, the idea of a “hit” has quietly broken down. The metrics still exist. The shared understanding does not.
Even the most successful formats on rival broadcasters now struggle to dominate in the way earlier generations did. Success is more fragmented, more platform-dependent and quicker to peak.
“There were hits,” one producer told me. “Just not in the way we used to recognise them.”
He paused, then added:
“Some of the shows that mattered most didn’t behave like hits anymore. Big Boys may define a generation more than anything on a bigger channel, but it doesn’t show up in the numbers the way commissioners used to expect. That’s not a Channel 4 problem. That’s the market.”
Audience attention is dispersed across platforms. Viewing is personalised and increasingly global. A program can have deep cultural impact without ever registering as a mass audience event. Large audiences no longer guarantee lasting relevance.
The industry still talks about hits. It no longer agrees on what one is.
Channel 4 did not create that condition. It made it visible.
“There was always a sense the channel thought it was doing better than the rest of us did,” one producer said. “And maybe it was, just not in ways we could easily measure.”
Others are more generous.
“The later slate felt stronger,” another supplier noted. “More confident. It felt like he grew into the role.”
Katz developed as a commissioner, and Channel 4 adapted under his leadership. It accelerated its shift toward streaming and maintained its reputation for distinctive, risk-taking content. It did not retreat into safety during a period of disruption.
But it never resolved the central challenge facing modern public service broadcasters: how to remain distinctive without becoming niche, and popular without becoming predictable.
That challenge is inseparable from Channel 4’s position within a London production ecosystem that increasingly feeds global platforms. Producers are no longer building businesses around a single domestic commissioner. They are developing ideas that must travel.
Channel 4 commissions locally. Its suppliers think globally.
If the linear slate reflected a strong editorial hand, digital often operated with far more freedom and far less clarity.
Producers describe a space where teams could experiment across YouTube and Channel 4.0 with minimal oversight, but without a clear strategic mandate. Digital sat between functions: development pipeline, marketing tool and commercial platform, without fully committing to any.
“There was freedom,” one digital producer noted, “but not always direction.”
The result was innovation that rarely scaled.
Attempts to bridge the gap rarely landed. Digital formats struggled to move onto linear without meaningful backing. Linear shows repurposed for digital were lightly tested and quickly dropped. Yet the potential was visible: low-cost, talent-led formats closer to creator content showed they could travel when properly supported.
The frustration is not that digital was overlooked. It is that it was never fully treated as a commissioning engine in its own right.
That same gap between idea and execution appeared in parts of the linear slate. Shows like reality format Rise and Fall and comedy horror Generation Z arrived with bold premises but struggled to convert that ambition into audience connection.
“They were clever on paper,” one producer said, “but you could feel the format admiring itself.”
In a fragmented market, attention is harder to win than ever.
Channel 4 is not just competing with other broadcasters. It is competing with a definition of success it cannot fully play by.
Katz did not resolve that contradiction. He made it unavoidable.
His successor will not simply be judged on editorial bravery. They will be expected to translate intent into scale, rebuild confidence with producers and deliver programs that not only provoke conversation but command audiences.
Katz did not fail that challenge. He clarified it.
Channel 4 has always defined itself by its willingness to challenge expectations. Under Katz, it became louder in doing so.
The question now is whether the next phase can connect that editorial sharpness to audience scale, and integrate digital not as an adjunct but as a core part of how the broadcaster commissions, develops and grows ideas.
Because in a landscape where attention no longer lives in one place, knowing what to say is no longer enough.
You have to know where it lands, and who it’s actually for.
