Interactive advertising revenues reached a new peak in the United States (U.S.) based on new data released by the IAB Internet Advertising Revenue Report.

The IAB revealed advertising revenues online hit an all-time high of $42.8 billion for 2013, which was enough to exceed broadcast television advertising revenues for the first time ever. Broadcast television advertising revenues equated to $40.1 billion.

For the Internet advertising revenues, the IAB stated it was a 17 percent increase from its previous peak of $36.6 billion in 2012. The fourth quarter of 2013 helped bring in $12.1 billion in advertising revenues, which is an increase from the $10.3 billion during the same quarter in 2012, or a 17 percent increase.

"The news that interactive has outperformed broadcast television should come as no surprise," said IAB CEO Randall Rothenberg. "It speaks to the power that digital screens have in reaching and engaging audiences."

The annual IAB report also disclosed that mobile advertising revenues encountered a triple digit growth compared to its previous year. Mobile advertising revenues grew by 110 percentage points from 2012's $3.4 billion as 2013's garnered $7.1 billion. As a result of 2013's mobile advertising revenues, mobile ads represented 17 percent of 2013's total revenues, an increase from the 9 percent in 2012.

Rothenberg added, "In that same vein, the staggering growth of mobile is clearly a direct response to how smaller digital screens play an integral role in consumers' lives throughout the day, as well as their critical importance to cross-screen experiences."

In addition to display-related advertising, digital video brought in $2.8 billion during 2013. For digital video, it was an increase from the $2.3 billion in advertising revenues in 2012, an increase of 19 percent. Digital video's revenues were enough to make it the fourth-largest format behind mobile. In total, display-related advertising garnered $12.8 billion in revenue for 2013, which represented 30 percent of the total year's revenues.

Revenues from search functions accounted for $18.4 billion, an increase from 2012's $16.9 billion.

The largest category in the Internet advertising spending is the retail advertisers, followed by financial services and the automotive industry.

As Latin Post reported, eMarketer estimated worldwide media spending on Internet-connected devices could hit $137.53 billion in 2014. The projected 2014 digital advertisement spending will be an increase of 14.8 percentage points when comparing 2013's $119.84 billion spending.

When it comes to global regions, North America is expected to continue its digital advertisement spending dominance between 2014 and 2018, largely due to spending in the U.S. Digital ad spending in North America is expected to account for 39.1 percent of the total worldwide spending in 2014, ahead of Asia-Pacific's 28.6 percent. Western Europe accounts for the third-highest digital advertisement spending with 23.2 percent projected.
