RECEIPT #MANDES
JUN 24, 2021
PREDICTION BY
Joe Mandese“Despite all the headlines, the death of the cookie will be delayed, deferred, and ultimately fudged. The industry isn't ready and Google knows it.”
FOLLOW-UP
Mandese called the cookie-death delay loop in 2021. Google delayed deprecation in 2021, again in 2022, again in 2024, and in July 2024 abandoned forced deprecation entirely. Vindicated repeatedly.

FOLLOW-UP
Shields called the holdco squeeze in 2020. WPP, Publicis, IPG all underperformed; Omnicom-IPG merged in 2024 and global headcount cuts hit every holdco through 2025.

PREDICTION BY
Garett Sloane“TikTok will be the next great ad platform. The brands that figure it out in 2021 will be the winners of the next five years.”
FOLLOW-UP

MAY 13, 2019
PREDICTION BY
Suzanne Vranica“The TV ad market is heading for a reckoning as audiences flee to streaming and the upfront model strains.”
FOLLOW-UP
Vranica flagged the TV upfront under stress in 2019. Linear TV ad revenue dropped from ~$66B (2019) to under $52B (2024); cord-cutting accelerated; CTV ate the difference.

FEB 09, 2023
PREDICTION BY

FOLLOW-UP
Kantrowitz called LLMs as a Google threat early. By 2025 Google search share dropped below 90% for first time in a decade and rolled out AI Overviews defensively, but core ad revenue still grew. Real but slower than predicted.

APR 26, 2021
PREDICTION BY
Ben Thompson“Apple's ATT will accelerate the shift to first-party data and benefit the largest platforms with logged-in users — Facebook included, eventually.”
FOLLOW-UP
Thompson predicted ATT would ultimately strengthen the biggest logged-in platforms despite short-term Meta pain. Confirmed: Meta rebuilt its ad stack with AI (Andromeda, Advantage+) and posted record revenue 2023–25, while small advertisers and the open web absorbed the damage.

RECEIPT #HWANG-
OCT 13, 2020
PREDICTION BY
Tim Hwang“The online ad market is a bubble that will pop, with consequences for the entire web economy that depends on it.”
FOLLOW-UP
Hwang's 2020 thesis: programmatic ads = subprime mortgages. ATT (2021), cookie deprecation, MFA-site exposés, and the open-web display crash partially validated it — but the ad market grew rather than imploded, propped up by retail-media and walled gardens.
