Google and Facebook dominance forecast to rise
Google and Facebook are set to attract 84 percent of global spending on digital advertising, excluding China, in 2017, according to a forecast from GroupM, the WPP-owned media buying agency, underscoring concerns that the two technology companies have become a digital duopoly. The research predicts that total global ad spending will increase by about $23 billion, or 4.3 percent, in 2018.
