Facebook and Twitter are making the biggest market share moves this year, and Facebook will increase its share from 5.82% in 2013 to 7.79% in 2014—by far the largest among the US-based companies included in our forecast. Twitter will see the next largest growth in market share among these companies, reaching 0.79%—up from 0.50% in 2013—by nearly doubling its net ad revenues year over year.
Both companies are benefiting from their users’ shifting behaviors on mobile devices. Facebook is expected to take 22.3% of the $32.71 billion global mobile advertising market this year, up from 17.8% in 2013. Twitter will continue its ascent in the mobile ad world as well, growing from 2.4% last year to 2.8% in 2014. Due to its continued success in search advertising, Google will maintain control of more than half of mobile advertising dollars worldwide, despite losing a small amount of share year over year.
