TV captured roughly $71.3 billion in domestic revenues in 2016 according to eMarketer, just under digital advertising’s $72.5 billion per the Interactive Advertising Bureau’s (IAB) digital ad revenue report. This is seen as big news within the ad community, but it is less a sudden seismic shift than an inevitable outcome of the proliferation of screens and the adoption of mobile devices.
