According to eMarketer, Google and Facebook accounted for about 63% of the digital advertising market in the US; 49% in the world. MediaPost suggests their market share could be between 60% and 70% in the US using data from various sources. Scary numbers?
A GroupM presentation at the UBS Global Media and Communications Conference in New York stated Google and Facebook will end 2017 with 84% of digital media investments (excluding China). How about now?
Still not scary enough?
