The global advertising market surpassed a half-trillion USD in 2014 totaling $525 billion with the top 10 countries accounting for nearly three-quarters of global advertising spend, according to new data from Strategy Analytics (www.strategyanalytics.com).

The United States alone accounted for over a third of global ad spend in 2014, 3.8 times higher than the second largest market, China, and over 16 times larger than Canada, the 10th largest market. Meanwhile China surpassed Japan in 2013 to become the second largest advertising market and will surpass Germany (4th largest market) and the U.K. (5th largest market) markets combined in 2015.

"While in absolute terms U.S. ad spend continues to grow its share of global advertising it is declining as spend in other regions grows." says Leika Kawasaki. "Despite this, the U.S. remains at #1 in ad spend across all media types and we do not anticipate this changing any time in the foreseeable future."

Other key findings from this report include:
