Surprisingly (although not to regular readers of Jack Myers TomorrowToday) the primary drivers of 2015 growth were legacy media, while digital media growth, while substantial, was slightly less than expected. Online originated video advertising increased 52% to $3.5 billion, compared to our original growth projection of 60%. Mobile and apps advertising (including mobile search) increased 62% to $11.3 billion, slightly weaker than our original forecast of 72% growth. Search and social marketing, both reported in our below-the-line data, performed as expected at 8% and 35% growth respectively. Online originated display advertising declined 4.0% to $7.2 billion, better than our original estimate of a 6.0% decline.

Among legacy media categories, digital advertising revenues grew at or below expectations, but traditional ad spending for some categories was significantly more positive than anticipated. Broadcast network legacy ad revenues declined 2.9% to $16.8 billion, compared to original expectations of 7.2% declines. Combined with digital growth of 16.0% (vs. expectations of 20%), broadcast network ad revenues declined 1.0% to $19.1 billion (excluding Hispanic, which will be reported separately). We are forecasting 2016 broadcast network total ad revenue growth of 6.6%.

Cable networks' combined legacy and digital ad revenues grew 1.4% in 2016, compared to anticipated 1.8% declines. Out-of-home/place-based advertising revenues was the beneficiary of growth well above expectations, with a reported increase of 6.3% compared to original projections of 0.5% declines. Cinema, local television and radio also performed better than originally estimated.

Both newspaper and consumer magazine ad revenues declined more than originally projected, with respective declines of 10.8% and 5.7% (Scroll down for 2015 details and a link to download our full 2015/2016 data and forecasts in PDF format.)
