From a Wall Street Journal story by Megan Graham headlined “Digital Ad Revenue Jumped 35% in the U.S. Last Year”:

Digital ad revenue in the U.S. jumped 35% to $189 billion last year as marketers chased consumers spending ever more time on online media and shopping, according to a new report from the Interactive Advertising Bureau and PricewaterhouseCoopers LLP.

The rise was well above the 12% growth rate of 2020, which was briefly hobbled by an early-pandemic dip. The year-over-year growth in 2021 was the highest the digital ad market had seen since 2006, when it rose at the same rate, the online-ad trade group said.
