A new report from IT research company Gartner forecasts a growth in mobile advertising spending this year, with the total global spend increasing to $18.0 billion (£10.9 billion) from last year’s estimated $13.1 billion total.

That growth is expected to continue for the next few years, with the mobile ad market being worth $41.9 billion (£25.4 billion) by 2017.
