U.S. ads spend is 2.5 times bigger than nearest competitor

The ad market in the United States is two and a half times bigger than its nearest competitor, China, according to new analysis by Zenith. The combined advertising spending of the other nine markets in the top ten just pass the ad spend in the U.S., rounding out to around $245 billion collectively.

The United States advertising market is huge, standing at roughly $229 billion dollars. Much of that size is now bolstered by digital ad spends. According to forecasts from PwC and IAB, digital ad spending surpassed traditional channels this year in the United States, hitting the $100 billion mark for the first time ever. Zenith predicts that growth in ad spending this year will move to 5 percent from their initial estimate of 2.9 percent.

Overall global online ad spending is expected to expand at a robust clip, with forecasts placing growth at around 4.7 percent. Much of that global development is estimated to come from online video and social media, which is set to grow by 19 and 14 percent respectively by 2021.
