Global Digital Ad Spending, 2010-2016 [CHART]

Worldwide, digital ad spending passed the $100-billion mark for the first time last year, according to new eMarketer estimates, and will increase by a further 15.1% in 2013 to $118.4 billion.

That will put worldwide digital ad spending levels—including online and mobile advertising spending, other than messaging-based formats—at 21.7% of the total spent on ads in all media this year, and on track to account for more than one-quarter of all ad spending by 2016. Read the rest at eMarketer.
