Google and Facebook, taken together, will account for about 63% of US digital ad revenues this year—and their share is growing.
With the duopoly taking in about two-thirds of US digital ad revenues, that leaves around a third of the market for every other firm to compete for. Most of that third is taken up by the long tail: Well over half of net US digital ad revenues at companies other than Facebook or Google go to firms outside the handful of major ad companies tracked by eMarketer.
Oath and Microsoft are tied as the largest individual digital ad firms outside the duopoly, with each expected to take 11.8% of the nonduopoly market this year. Third-place Amazon is far behind, with 5.4%, but will close the gap significantly by 2019, even as Twitter will lose share—and its No. 4 ranking—to Snapchat. Read the rest at eMarketer.
