Notes: Facebook will grow to account for 20.3% of all US mobile ad spending in 2017, up slightly from an estimated 19.4% share this year and 18.5% last year, per eMarketer’s latest estimates. (That would be in line with the 19% of mobile internet time spent with Facebook.) While Facebook’s share of mobile ad revenues is expected to grow slightly, the opposite is true for Google, which is projected to see a sizable decrease in revenue share this year (from 36.9% to 32.9%).
Separately, Google (40.1%) and Facebook (13.2%) are projected to account for a majority (53.3%) share of all US digital ad revenues (not just mobile) this year. If other eMarketer estimates hold true, that would mean that those two companies alone would capture more US media ad spend than all of print media.
About the Data: The eMarketer estimates are net ad revenues after companies pay traffic acquisition costs (TAC) to partner sites. They include display (banners and other, rich media and video), search and messaging-based advertising, and ad spending on tablets.
