In-app mobile adspend will reach $16.9 billion by 2018, up from $3.5 billion last year, and will be driven by data and interactive rich media advertising.
The report, conducted by Juniper Research says that it will be tablet users. Currently the smartphone market accounts for 70% of current adspend, a stake that will dip to 50% in 2018, on the same level as tablets.
While app downloads will increase exponentially to 2018, the majority of in-app advertising expenditure is likely to be spent on advertising with social mobile giants such as Facebook and Twitter.
