Research by Enders Analysis shows that between 2022 and 2023 the average age of Channel 4’s biggest hits was nine years. For ITV, this figure stood at 11.
Tom Harrington, the head of television at Enders Analysis, says: “This is one of those metrics that can be taken both ways. Reliance on older formats seems the antithesis of innovation. But at the same time, surely it’s a good thing if you have a show that commands strong audiences for 10-plus years?”
