Total global revenue from mobile media and advertising will pass $90 billion (€66 billion) in 2018 up from $53 billion in 2014, according to a new report from IHS. The research company said mobile advertising will become the leading mobile business model, overtaking paid content revenues in 2015. Meanwhile in-app purchases will remain the primary revenue stream for app developers as mobile search remains higher than mobile display advertising revenues. The report added that wearable apps provide new opportunities, but business models must evolve in order for these opportunities to be exploited. Report
