We present a data-driven study on which sources were the rst to report on news events. For this, we implemented a news-aggregator that included a large number of established news sources and covered one year of data. We present a novel framework that is able to retrieve a large number of events and not only the most salient ones, while at the same time making sure that they are not exclusively of local impact.
Our analysis then focuses on di erent aspects of the news cycle. In particular we analyze which are the sources to break most of the news. By looking when certain events become bursty, we are able to perform a ner analysis on those events and the associated sources that dominate the global news-attention. Finally we study the time it takes news outlet to report on these events and how this re ects di erent strategies of which news to report. A general nding of our study is that big news agencies remain an important threshold to cross to bring global attention to particular news, but it also shows the importance of focused (by region or topic) outlets.
