Media owners’ advertising revenues will decrease by $42 billion in 2020, from $582 billion to $540 billion, as advertising spending shrinks due to the severe economic recession triggered by the COVID-19 pandemic, as GDP is expected to contract between -5% and -12% across the world’s largest markets. Global advertising revenues will decrease by an estimated -7%, as the heavy, double-digit decline of linear ad sales (linear TV, print, linear radio, OOH, cinema), -16% to $238 billion, will be mitigated by the stability of digital formats: +1% to $302 billion.
