  It is known that news topics, covered more frequently and over longer periods
of time, are considered to be important to the public. Hence, what gets media
attention and how media attention evolves over time has been studied for
decades in communication study. However, previous studies are confined to a few
countries or a few topics, mainly due to lack of longitudinal global data. In
this work, we use a large-scale news data compiled from 196 countries to
provide empirical analyses of media attention dynamics.
