Seventy-five percent of internet use will be mobile in 2017, up slightly from this year, as a growing number of consumers around the world access the web on smartphones and tablets, media buying agency Zenith forecast this week.  Zenith previously estimated that 71 percent of internet consumption would be mobile in 2016. Sixty percent of global internet advertising dollars will come from mobile advertising in 2018, Zenith said, following the release of its “Mobile Advertising Forecasts” report on Thursday.  Mobile advertising expenditure in 2018 will total $134 billion, which “is more than will be spent on newspaper, magazine, cinema and outdoor advertising put together,” it said.
