Dynamics of Media Attention

TL;DR

This paper investigates traditional media attention dynamics by analyzing co-occurrence of people in newspaper articles, revealing different regimes at short and long time scales with bursty and Poissonian behaviors.

Contribution

It introduces a novel analysis of media attention in traditional outlets, highlighting distinct short-term bursty and long-term Poissonian regimes.

Findings

Short-term dynamics show burstiness and rapid decay of attention.

Long-term dynamics exhibit Poissonian behavior and slower decay.

A cascading Poisson process model explains the observed regimes.

Abstract

Studies of human attention dynamics analyses how attention is focused on specific topics, issues or people. In online social media, there are clear signs of exogenous shocks, bursty dynamics, and an exponential or powerlaw lifetime distribution. We here analyse the attention dynamics of traditional media, focussing on co-occurrence of people in newspaper articles. The results are quite different from online social networks and attention. Different regimes seem to be operating at two different time scales. At short time scales we see evidence of bursty dynamics and fast decaying edge lifetimes and attention. This behaviour disappears for longer time scales, and in that regime we find Poissonian dynamics and slower decaying lifetimes. We propose that a cascading Poisson process may take place, with issues arising at a constant rate over a long time scale, and faster dynamics at a shorter time scale.
