Us Online Ad Revenue Share By Company, 2012-2016 [TABLE]
Facebook’s share of the US digital display market rose from 14.8% in 2012 and is projected to hit 21.5% this year, according to our projections, while Twitter had only 1.5% of the digital display market two years ago, but is expected to more than double its share by the end of this year, increasing to 3.5%.
While most social networks require users to be logged in to see and interact with advertising, anyone can view Tumblr ads. Our estimates for Tumblr users include those who log into the platform on a regular basis, so this figure represents the number of blogs on which Yahoo’s advertisers can publish as well as it does audience size.
