Five of the world's largest tech companies owned more than half (53%) of all global ad revenues last year, up from 46% last year.
Why it matters: Macroeconomic factors like inflation and rising wages are making it harder for new entrants to disrupt the ad market, analysts explain in the latest midyear ad forecast from GroupM.
The big picture: Ten years ago, the top five advertisers were mostly U.S. media companies: Google, Viacom and CBS, News Corp and Fox, Comcast and Disney.
What's next: The global ad market is expected to grow by 8.4% this year (excluding U.S. political advertising), a slightly lower forecast than what experts initially predicted for 2022.
Yes, but: Publishers shouldn't panic. It's a "deceleration, not a decline," said Brian Wieser, global president of business intelligence at GroupM.
