🌯 Ad Dollars and Google Antitrust Drama: 2024’s Banner Year, 2025’s Bumpy Ride

AdMonsters Wrapper: The weekly ad tech news wrap up

Hey Monsters,

Breaking news:
A federal judge ruled Thursday that Google illegally maintained a monopoly in online advertising technology. The link between Google’s ad server and ad exchange was deemed anticompetitive. To all the publishers who complained for years about Google's ad server, and how they couldn't optimize yield because of all of its restrictions: take a moment to reflect on this conclusion.

The ad ops community actually played a part in a major antitrust trial. All those technically nuanced details – about dynamic allocation and waterfalls and ad prioritization – decided a case. Tell that to your family at Thanksgiving.

We are going to be covering the impact of this decision more, so email me with your reactions. What do you think this will mean for you as a publisher? We want to know, and we want to share your POV with our community. So drop me a line – abyrd@admonters.com – to be included in our reaction coverage.

Now let’s zoom out for our regularly scheduled programming. If 2024 felt like a trip through the funhouse—AI breakthroughs, streaming shakeups, and election-year ad blitzes—2025 is shaping to be game-changing in more ways than one. As we reflect on 2024 with the IAB's latest Internet Ad Revenue Report detailing the highs and lows 2024, we can't help but look forward and strategize for the whirlwind of 2025.

So grab your coffee, stretch out those scrolling fingers, and let's dig in: What did 2024's ad spend bonanza mean for publishers, and what's the outlook as we stare down another year full of promise and plot twists?

IAB Reports Ad Spend Surge in 2024...But 2025

Ad Spend at a Crossroads—2024’s Record Growth Meets 2025’s Uncertainty
Digital ad revenue in the U.S. hit an all-time high of $259 billion in 2024—a 15% year-over-year surge and the fastest pace of growth since 2021. A combination of high-stakes events, including the U.S. Presidential Election and the Summer Olympics, drove advertiser demand and fueled major budget increases.

Formats delivering both reach and engagement saw the biggest gains:

Search continued to lead the pack, generating $102.9 billion and accounting for nearly 40% of all digital ad spend.

Digital video was the standout, growing 19.2% year-over-year to $62.1 billion and capturing nearly a quarter of the market.

Display followed with $74.3 billion (up 12.4%), while social media surged 36.7% to $88.7 billion—boosted by the boom in creator-led content.

Retail media also maintained its momentum, climbing 23% to $53.7 billion as brands leaned heavily into first-party data and privacy-safe targeting.

Podcasting made a strong comeback, growing 26.4% to reach $2.43 billion.

One of the more surprising developments was the rise of mid-tier publishers. These media companies saw the fastest growth in market share, gaining over 3% as advertisers spread budgets beyond the top platforms in search of brand-safe, engaged audiences.

“These midsized companies are adopting new business models, encouraging creator engagement, and leveraging AI and data-driven insights to offer more personalized, cost-effective advertising solutions,” said David Cohen, CEO, IAB.

Looking Ahead: 2025’s Promise and Peril

That’s 2024 in the books – so how’s 2025 looking?

When Dentsu released its 2025 projections report at the end of 2024, the forecast painted an optimistic picture for global advertising this year, projecting a 5.9% increase in ad spend, with digital channels expected to grow even faster at 9.2% and capture over 62% of total budgets.

But these projections came before Hurricane Trump.

A wave of uncertainty introduced by the Trump Administration's fluctuating tariff proposals tempered this optimism. As advertisers and agencies gather for this year's upfronts, many find it challenging to make long-term commitments amid the unpredictability of new tariffs on China and other nations.

“It’s really bananas going back and forth like this,” David Campanelli, president of global investment for the ad-buying firm Horizon Media, told the LA Times. “What we’re hearing from advertisers is that they are still waiting to understand the impact that tariffs will have on their business and how it will impact people’s willingness to pay more.”

Brands are actively preparing best- and worst-case scenarios, wary of how increased costs and potential consumer pullbacks could impact ad performance and spending. For instance, Omnicom has trimmed its 2025 organic growth outlook, citing uncertainty from tariffs and macroeconomic pressures. It is now expecting 2.5–4.5% growth (down from earlier, more optimistic projections).

Some analysts, like those at Moffett Nathanson, warn that a recession triggered by tariff-related economic shocks could reduce 2025 ad spending by as much as $45 billion, disproportionately affecting digital and TV budgets.

And with the news of DOJ's Google ruling, who knows where ad revenue will sit by the end of the year.
