Advertising

PREDICTION BY

FOLLOW-UP

The year 2024 is concluding, and while official final numbers for online ad spending and waste are not yet fully available, early indicators and ongoing industry discussions suggest a significant portion of digital ad spend continues to face challenges like fraud and inefficiency, aligning with Hoffman's concern about 'wasted' billions.

PREDICTION BY

FOLLOW-UP

This is a multi-year forecast extending beyond 2025, and it is too early to determine the outcome. No information in the provided snippets confirms or denies this prediction.

PREDICTION BY

FOLLOW-UP

Wieser's December 2024 prediction of 4.5% growth for 2025 was subsequently downgraded to 3.6% by March 2025, confirming the prediction that he would 'tamp down' expectations for the new year (2025).

PREDICTION BY

FOLLOW-UP

While later forecasts mention digital share projections, the provided snippets do not contain specific realized data on digital ad revenue growth for 2024 to confirm or deny the 10.7% prediction.

PREDICTION BY

FOLLOW-UP

While Wieser maintained his expectation of H2 2024 deceleration as of September 2024, the strong Q2 performance (9.6% growth) contradicted an *imminent* slowdown. The provided snippets do not contain actual realized Q3 and Q4 2024 growth figures to definitively confirm or deny the H2 deceleration.

PREDICTION BY

FOLLOW-UP

Wieser's March 2024 forecast of 5.6% growth for the U.S. ad industry in 2024 (excluding political) was later revised upward repeatedly to 7.2% by September 2024, indicating the actual performance was stronger than initially predicted in March.

PREDICTION BY

FOLLOW-UP

This qualitative prediction describes a structural shift. The rise of AI-driven recommendation and search systems is indeed shifting focus towards optimization for AI (AEO/GEO), indicating a fundamental change, but its full impact is still developing.

PREDICTION BY

FOLLOW-UP

Given the very recent date, this prediction is an extrapolation of ongoing trends. AI-generated creative is increasingly prevalent and, in some cases, achieving high quality and performance, aligning with his assertion.

PREDICTION BY

FOLLOW-UP

Global ad spend data shows digital advertising (with mobile as the majority) surpassing TV and print advertising. Mobile-first campaigns are now standard, and mobile ad spend exceeds TV in many markets.

PREDICTION BY

FOLLOW-UP

As of August 2026, early evidence is directionally consistent but not conclusive. Major streaming platforms continue to expand ad-supported offerings, indicating increased advertising integration. Industry forecasts for 2025–2026 project continued growth in global ad spend and a rising share of total corporate revenue from advertising. However, as this is a 'multi-year structural forecast,' the full long-term outcome is still in progress.

PREDICTION BY

FOLLOW-UP

As of August 2026, it is too early to definitively evaluate the '75-80% AI reckoning' for agency media profits. Some early signs of AI buying tools and client experimentation are observable, but the quantitative impact on agency profits is not yet measurable. The descriptive portion about 40-45% direct ad spend is a contemporary assessment rather than a prediction outcome.

PREDICTION BY

FOLLOW-UP

Industry data and commentary through 2023 consistently described a tougher environment for advertising, especially in traditional TV and some brand-building budgets, due to higher interest rates and cautious corporate spending. Many reports characterized 2023 as a 'testing year' with slower growth and more volatility, consistent with Whittaker's forecast. While not a uniform collapse, the impact was directionally correct with a challenging and lower-growth year.

PREDICTION BY

FOLLOW-UP

Global advertising forecasts and early-2024 trading updates broadly characterized 2024 as a growth year for ad spend, with continued strength in digital platforms, aligning with his description of a 'benign' environment and advertising 'doing quite well'. Macro conditions (inflation moderating, interest rates stabilizing) supported continued, though uneven, growth, consistent with a good but not exceptional year.

PREDICTION BY

FOLLOW-UP

As of mid-2026, two years have not fully elapsed since the prediction (made August 2024). While TikTok/Bytedance grew, Meta remained larger in global revenue and user reach across its platforms. The timeframe for 'within two years' is still active, but the full 'usurping' has not occurred yet.

PREDICTION BY

FOLLOW-UP

Alphabet's business performed strongly through 2024-2025, with revenue and share price growing materially, making it a strong performer among large-cap tech companies and supporting the prediction of it being a good stock pick.

PREDICTION BY

FOLLOW-UP

This quote describes the power imbalance in negotiations with Google regarding AI partnerships and content licensing. The outcome of these negotiations and the future landscape of deals between Google and publishers is still developing.

PREDICTION BY

FOLLOW-UP

This is a forward-looking statement about reinvesting savings from improved frequency capping. There is no evidence in the provided context to confirm if these savings have been realized or reinvested.

PREDICTION BY

FOLLOW-UP

Pritchard's observation about AI moving from theory to practice in 2024 aligns with the provided information, which states P&G is seeing real productivity boosts from AI in ads, including testing ads in hours rather than weeks.

PREDICTION BY

FOLLOW-UP

Perplexity publicly announced and rolled out advertising formats within its AI answer engine in late 2024, validating the article's statement that it 'will introduce an advertising product'.

PREDICTION BY

FOLLOW-UP

The four-year timeframe for OpenAI to have a scaled ad platform has not elapsed; as of mid-2026, the prediction remains untested.

PREDICTION BY

FOLLOW-UP

While Meta and TikTok introduced pay-or-okay models in the EU by the end of 2024, not every scaled social media platform universally adopted such a model.

PREDICTION BY

FOLLOW-UP

Major ad platforms (Meta, Google, Amazon Ads, TikTok) have deployed generative AI tools for creative and AI-driven predictive targeting/optimization, integrating them into standard campaign workflows, consistent with Thompson's prediction.

PREDICTION BY

FOLLOW-UP

This early-2024 forecast understated the eventual strength of the market. It was superseded by his own later upward revisions, and compared to actual outcomes, is best viewed as a conservative starting point that proved too low.

PREDICTION BY

FOLLOW-UP

The specific 2028 numbers cannot yet be verified, but interim growth data (2024–Q2 2025) show accelerating growth in commerce media in the 19–24% range, which is on pace for the forecast.

PREDICTION BY

FOLLOW-UP

Too early to fully validate the 2028 end-point, but interim data (2023–2025) support his projected direction and pace of rising digital share.

PREDICTION BY

FOLLOW-UP

The forecast of 10.5% growth including political ad spending is consistent with later industry tallies and the qualitative prediction of a "banner year for political ad spending".

PREDICTION BY

FOLLOW-UP

Meta has indeed rolled out AI-driven ad tools for creative generation and optimization, with the company and analysts attributing improved ad effectiveness and revenue growth to these advancements.

PREDICTION BY

FOLLOW-UP

Meta, Google, and Amazon have all heavily integrated AI into their advertising platforms, leading to new ad formats, better targeting, and improved performance, fulfilling the prediction that AI would unlock new possibilities.

PREDICTION BY

FOLLOW-UP

WhatsApp has become a key growth driver for Meta, while Facebook's growth and cultural centrality have slowed.

PREDICTION BY

FOLLOW-UP

2024 saw significant layoffs, financial stress, and consolidation within institutional media, consistent with a "horrible year" for the sector.

PREDICTION BY

FOLLOW-UP

Meta has continued to push Advantage+ and AI-driven campaign formats, encouraging objective and budget-based advertising, with reported strong performance gains for advertisers.

PREDICTION BY

FOLLOW-UP

This prediction has a four-year horizon (roughly 2024-2028). While OpenAI has moved towards monetization, a fully scaled ad platform comparable to major ad networks is not yet in place by mid-2026, making it too early to definitively evaluate.

PREDICTION BY

FOLLOW-UP

Meta expanded its AI-driven creative and ads tooling, explicitly targeting gaming advertisers with automated creative formats and AI-generated creatives tuned to verticals like gaming.

PREDICTION BY

FOLLOW-UP

This forecast appears to have been broadly validated by later discussions of 2024 as a ~10.5% growth year including political, with subsequent commentary treating this as a realized benchmark.

PREDICTION BY

FOLLOW-UP

Actual Q1 2024 U.S. ad spend (excluding political) grew 10.1%, exceeding Wieser's 8% forecast.

PREDICTION BY

FOLLOW-UP

Wieser later revised his 2024 U.S. ad spending growth forecast upward multiple times, ultimately to 7.2% (excluding political), indicating the market was stronger than his initial 5.6% prediction.

PREDICTION BY

FOLLOW-UP

By 2025-mid-2026, YouTube solidified its role as a central video and creator platform, becoming a leading platform for podcast distribution and consumption, and showing strong growth in Connected TV (CTV) ad dollars. Podcasts continued to grow as an ad-supported medium with high engagement. This prediction has been substantially borne out, with YouTube's centrality to video, streaming, and podcast advertising widely acknowledged.

PREDICTION BY

FOLLOW-UP

TikTok's share of attention and marketing budgets increased, becoming a more central video platform. However, streaming services continued to grow subscribers and ad revenue, particularly via ad-supported tiers. The prediction was directionally right about competitive pressure, but without clear share-loss or structural damage to Netflix/Spotify's core businesses.

PREDICTION BY

FOLLOW-UP

Retail media networks, as exemplified by Amazon, Walmart, Instacart, and Uber, have continued rapid growth since 2024, validating the 'everything is an ad network' thesis in the context of privacy restrictions impacting social media advertising.

PREDICTION BY

FOLLOW-UP

By mid-2026, retail media networks, performance-based walled gardens, and outcome-guaranteed buying models are gaining share. DSPs and networks increasingly emphasize 'outcome-based' buying over impression-based metrics, aligning with the prediction's direction. This is an evolving trend.

PREDICTION BY

FOLLOW-UP

The prediction's timeframe extends to around 2028. As of late 2025, OpenAI has not yet launched a full-scale ad platform, but the prediction window is still open, and the outcome is evolving.

PREDICTION BY

FOLLOW-UP

Microsoft did not launch a full mobile gaming store or a dedicated ad product for such a store in 2024. While Microsoft is invested in gaming and ads, the specific forecast did not materialize.

PREDICTION BY

FOLLOW-UP

By mid-2026, Apple and Google have continued to strengthen their control of ad channels and grow ad revenues, aligning with Thompson's prediction. Apple's Search Ads and Google's overall ad business have shown strong growth, leveraging platform control and privacy-focused ad solutions. The trend supports his forecast of their primary benefit from changes in advertising.

PREDICTION BY

FOLLOW-UP

Retail media networks continued to proliferate in 2024-2025, and other sectors developed ad businesses based on first-party data, supporting the continuation of this trend.

PREDICTION BY

FOLLOW-UP

Microsoft did launch a mobile ad network in 2024, fulfilling the 'ad product' part. While a full 'Microsoft mobile gaming store' as a distinct app store did not materialize, the ad product itself was launched.

PREDICTION BY

FOLLOW-UP

Microsoft did launch a mobile ad network called 'Microsoft Mobile Ad Network' in 2024, primarily for its own mobile titles, which aligns with 'a mobile gaming advertising product'.

PREDICTION BY

FOLLOW-UP

While Meta implemented pay-or-okay, not all scaled social media platforms adopted a full ad-free subscription model in the EU by end of 2024.

PREDICTION BY

FOLLOW-UP

Meta expanded and promoted its AI-driven creative tools for app and gaming advertisers in 2024, consistent with bespoke tools for gaming creative.

PREDICTION BY

FOLLOW-UP

Linear TV's ad share has continued to decline, and industry forecasts and observed data support it falling below 50% by 2028.

PREDICTION BY

FOLLOW-UP

As of the mid-2020s, Google continues to derive the vast majority of its revenue from advertising, and has been actively integrating Gemini into its ad products, search experience, and YouTube, reinforcing its strong position in AI-enhanced advertising and supporting Nathanson’s optimism. OpenAI, by contrast, has focused primarily on subscription and enterprise models (e.g., API access, ChatGPT subscriptions, enterprise licenses), with no large-scale, mature display or search advertising business comparable to Google or Meta; this aligns with his view that building a successful ad business around OpenAI’s products would be “extremely difficult.” Whether OpenAI “may never succeed” in advertising is still an open question, but the observable trajectory to date—limited direct ad monetization vs. heavy enterprise/subscription focus—has so far supported his skepticism.

PREDICTION BY

FOLLOW-UP

By 2024–2025, AI-driven creative and optimization tools (image/video generation, copy optimization, dynamic creative, predictive targeting) became widely adopted across major advertising platforms and agencies, with demonstrable improvements in click-through rates, conversion metrics, and measurement granularity—matching his description that AI would “turbo-charge” impactful messaging and make creative more quantifiable. Leading ad-supported streamers and digital platforms increasingly highlight AI-enhanced targeting, measurement, and creative as key drivers of ad effectiveness and pricing power, consistent with his view that the “unit value” of advertising is poised to soar due to AI.

PREDICTION BY

FOLLOW-UP

Shields himself states the prediction was wrong, citing the continued and expanding role of advertising in streaming services.

PREDICTION BY

FOLLOW-UP

After launching its ad-supported tier in late 2022, Netflix’s ad business grew steadily but from a small base, attracting budgets from brand advertisers and shifting spend away from other video platforms; industry estimates by 2025 place Netflix ad revenues in the low-single-digit billions of dollars, broadly consistent with his “three billion or so in a couple years’ time” directional forecast. That growth reflects exactly what he described: new advertising dollars flowing to Netflix and/or being reallocated from other parts of the video ad ecosystem.

PREDICTION BY

FOLLOW-UP

Multiple industry reports later characterized 2023 as a very soft ad year, with flat to slightly negative nominal growth in several major markets despite the absence of an official recession, validating the direction of Nathanson’s forecast. Linear TV ad revenues did decline mid-single digits or worse, while ad-supported streaming and digital video saw healthy double-digit gains, closely matching his structural call: shrinking legacy linear, partially offset but not fully replaced by growth in AVOD/SVOD ad tiers. His specific framing—“first time in a non-recessionary year that you see negative growth”—is directionally supported by how unusual 2023 looked relative to past non-recession years.

PREDICTION BY

FOLLOW-UP

Global and U.S. ad spend data from major tracking firms show high-teens digital growth and low-single-digit total growth in 2018, broadly consistent with Nathanson’s forecast. Traditional media (especially print and linear TV) did decline in aggregate in 2018, while digital (search, social, online video) grew strongly, matching the direction and rough magnitude of his prediction.

PREDICTION BY

FOLLOW-UP

An AI-targeted content market has started to form with licensing deals, but these have not broadly “saved” advertising-based publishing, which continues to struggle. AI overviews and answer boxes in search engines have begun to reduce dependency on traditional link-based search. The direction of the prediction is verifiably correct: AI is accelerating pressure on ad-funded publishers, and the emerging AI content/licensing market has not transformed their fortunes.

PREDICTION BY

FOLLOW-UP

Through the end of 2024, Microsoft did not launch a widely documented, dedicated, Microsoft-branded mobile gaming advertising network or product on the scale of Apple Search Ads or Google Ads specifically for mobile game distribution. Microsoft advertising products remained focused on search (Bing), display, and retail media.

PREDICTION BY

FOLLOW-UP

By mid-2026, consumer AI products are indeed increasingly leveraging advertising-linked monetization and profile-driven targeting, especially at major tech companies. This supports Thompson’s view that advertising is a highly effective way to monetize large-scale AI usage. However, some leading AI labs also maintain substantial subscription and B2B/enterprise revenue, so advertising is a primary path, but not the exclusive one, and other paths are still significant.

PREDICTION BY

FOLLOW-UP

FAST channels featuring creator content expanded, with streaming services curating channels built around social/creator personalities and repackaged UGC-style formats. Collaborations between streamers and creators increased, with major streaming brands running projects where YouTube/TikTok creators co-host or extend studio IP. The economic rationale (lower production costs, higher engagement) also proved accurate.

PREDICTION BY

FOLLOW-UP

Major streamers deepened or launched partnerships with retail media networks, creating clean-room style data collaboration. Measurement providers and streamers expanded multi-party data clean rooms and cross-publisher IDs for CTV. Streaming ad products increasingly marketed first-party viewer data and collaboration tools as a key differentiator.
