TV news is the most expensive kind of news to make. Doing it with one of the smallest budgets in the business is even harder.
The programme mixes deathly serious reports from war zones and foreign crises, domestic news and live interviews with a playfully irreverent streak.
So how does a TV news designed for a younger viewers make sure it stays relevant?
The day BuzzFeed visited, anchor Jon Snow was celebrating 25 years on the programme. He started presenting Channel 4 News in 1989. We asked him to sum up what the show means to him.
This is from Snow's first ever Channel 4 broadcast.
Snow cringes at the mention of this early broadcast and impersonates himself doing some plummy Queen's English to show how his accent has changed.
He says he’s as happy now anchoring the show as he ever was. He's looking forward to reporting from Scotland this week, testing the nation's mood on the forthcoming referendum.
He was at the fall of the Berlin Wall but the 9/11 attacks stand out as the most memorable story so far, he says. But do news presenters understand, in that moment of telling viewers about world-changing events, the gravity of the situation?
“9/11 was unfolding live in front of us and we had no idea it would change the whole dynamic of the world. You had a sense that what’s happening is big, but you didn’t think it was tectonic.”
