Net US Online Ad Revenue Share By Company, 2012-2016 [TABLE]

The accelerated rise in ad spending is being influenced in part by growing revenues from leading internet media companies, particularly those that are capitalizing on mobile revenues. eMarketer projects advertising revenues for a handful of the top US digital ad-selling companies, which collectively will represent 18.2% of total media ad spending this year—led by Google and Facebook. Google alone already accounts for more than 10% of all advertising spending in the US, and in 2016, together Google and Facebook will take a 15.0% share of the $200.00 billion total media advertising market. Mobile ads on Facebook will total 68.0% of its US ad revenues this year, up from 46.7% last year, eMarketer estimates, and while Google’s ad revenues in the US won’t flip to majority-mobile until 2016, they’re shifting quickly. This year, Google’s US mobile revenues will comprise only 36.8% of its overall ad revenues, but by 2016, the medium will account for 65.8%. Read the rest at eMarketer.
