US Digital ad spend to grow 15.9% this year: eMarketer
Digital ad spend in the US will grow 15.9% this year, with Facebook's ad revenue projected to jump 32.1% and Google's by 14.8%, according to eMarketer. Most of Google's income comes from search, for which it claims $28.5bn of the $36.7bn market. However, by next year, Google's search revenues are expected to bring in $32.4bn of the forecasted $40.5bn industry. For the mobile ad market, Google comprises 32.4% of spend, while Facebook generates 24.6%. EMarketer noted that Facebook-owned Instagram will make up 20% of its parent company's US mobile revenue this year, up from 15% last year.

The so-called duopoly between Facebook and Google to control the bulk of digital ad spend is far from over, according to eMarketer.

The firm’s newest forecast expects for digital ad spend in the U.S. to grow 15.9 percent this year—the equivalent of $83 billion in revenue. Within that growth, Facebook’s ad revenue is projected to jump 32.1 percent while advertisers’ spend with Google will increase 14.8 percent.

Overall, Google controls 40.7 percent of the U.S. digital ad market, followed by Facebook with 19.7
