After several false starts, mobile advertising has now truly taken off and is forecast to account for 37% of all growth in global ad expenditure this year, and 31% in 2014, according to a recent report by ZenithOptimedia.
Mobile advertising (defined in the report as internet ads delivered to smartphones and tablets, whatever their format) is still relatively small—with a total spend of $14.3 billion worldwide this year, or 2.8% of total ad expenditure.
However, it is growing extremely rapidly: 77% growth in 2013, followed by 56% in 2014 and 48% in 2015, ZenithOptimedia forecasts. By 2015, mobile ad spend is expected to total $33.1 billion and to account for 6% of total ad expenditure.
