Ask HN: Is there a resource to track the flow of news stories across the globe?

Even something as "simple" as flow of news headlines across major news agencies (like Reuters, AFP, AP, TASS, etc) across countries would be really interesting. Such a resource could potentially reveal the sources of specific stories (with enough granularity of data) or which news sources weild the most influence over a region. For example, something like this quick mock-up I did: https://imgur.com/a/hRa41Vg
