Mobile search and display advertising up 220% in US alone
eMarketer
Mobile ad spending around the world more than doubled last year, eMarketer estimates, and though growth will moderate this year, double-digit increases in mobile ad spending will continue in coming years as outlays approach $37 billion by 2016.
In 2012, mobile spending was at $8.41 billion, according to eMarketer’s forecast—up from just over $4 billion the year before and $2.34 billion in 2010. eMarketer’s estimates of worldwide mobile ad spending include dollars going toward display and search advertising only, and exclude spending on messaging-based formats. Spending on tablets is also included.
