Mobile advertising spend in the UK will reach £999m by the end of 2013, according to eMarketer forecasts. Thats up 90 per cent on last years figure of £526m.
By comparison, overall digital spend is set to rise just 12 per cent in the same period, with mobile accounting for the majority of this increase.
Mobile spend will rise by a further 60 per cent in 2014, to £1.6bn, and by a CAGR of 38.8 per cent over the next four years to reach £3.7bn by 2017.
Ad spend vs time spend 
This year, mobile will account for 16.5 per cent of digital ad spend and 7.2 per cent of total UK media spend.
Comparing this figure of 7.2 per cent with data from Mary Meekers latest Internet Trends report, ad spend still isnt keeping up with mobiles share of time spend. Meekers numbers – which are admittedly US-based – show that mobile accounted for 12 per cent of all time spent in media.
eMarketers forecasts see mobile ad spend (10.9 per cent) nearly matching this by 2014 – though by then, consumer behaviour will likely have shifted again, and mobile could hold an even higher proportion of time spend.
