Sometimes publishers get so hung up on new, shiny things that they forget to look at what their audience really values.

Slovakia's Denník N is well-known for innovative journalism in a country that's fairly hostile to independent media. Their latest innovation involves 130-year-old technology.

Slovakia’s Dennik N’s bold campaign brought 10,000 new subscribers in just four days
The news organisation asked readers to pay what they wanted - even nothing - and promised to “keep monitoring depressing news so they wouldn’t have to.” The result? Its biggest subscription spike ever

Patricia Vo'anská runs the newest areas of the newsroom like podcasts, video and social media. She now oversees, somewhat ironically, the launch of a good, old-fashioned FM.

She wasn't sold on the idea at first, but she underestimated the number of people who still listen to radio. Surveys say over 80 per cent of people in Slovakia - a country with around 5 million inhabitants - use classic FM, mostly in the car or at work, and about half the country also listens to online streams.

"Over three million people [listen to radio], and the numbers have stayed stable for years," says Voľanská.

"After I went through the data, it started to feel irresponsible to ignore them [radio listeners]. We already produce a huge amount of audio, and here is a channel that can bring it to people. It would be a mistake not to at least try."
