50 Things That Made the Modern Economy


50 Things That Made the Modern Economy is a radio show and podcast on the BBC World Service. It is presented by economist and journalist Tim Harford. The first series was broadcast between 5 November 2016 and 28 October 2017. A second series began on 30 March 2019.
Harford explained in a BBC interview in 2017 that his motivation for creating the show was "to paint a picture of economic change by telling the stories of the ideas, people, and tools that had far-reaching consequences". He was "fascinated" by the many unexpected outcomes, such as "the impact of the fridge on global politics, or of the gramophone on income inequality."
Towards the end of the first series, a public call was made for suggestions of a "51st thing". Harford chose six submissions for an online vote. The winning item was announced as the credit card in an episode on 28 October 2017. A bonus episode about Santa Claus was broadcast on 24 December 2018.
The first series was published in Britain as Fifty Things That Made The Modern Economy. by Little, Brown, and as Fifty Inventions That Shaped The Modern Economy in the US by Riverhead. Reviews of the book were mixed.
The show won a silver award for "Best Radio Podcast supported by UK Radioplayer" at the 2017 British Podcast Awards.
