Domestic digital advertising revenue surged 19% to $27.5 billion during the first six months of 2015, a landmark high for the industry since the Interactive Advertising Bureau began tracking the information nearly two decades ago.
Second-quarter internet ad revenue also rose by 22.5% to $14.3 billion, up from $11.7 billion from the first half of last year, according to a report released Wednesday by the IAB and prepared by PwC.
Advertisers continue to invest dollars in mobile, as revenue climbed to $8.2 billion for the first half of 2015, up about 54% from $5.3 billion reported from the first half of last year. Mobile now represents 30% of all revenue generated by digital advertising.
Emerging markets such as social media also continue to show growth, as revenue delivered on the space reached $4.4 billion during the first half of 2015, a 51% increase over the same period a year ago. Social media revenue includes websites like Facebook or Twitter, as well as social gaming websites and apps, the IAB said.
