Interpretation
Ad Tech Architecture & Platforms Interpretation
In 2023 the ad data economy was already a $12.0 billion audience marketplace while programmatic still funneled most spend through RTB, and by 2024 the stack looks even more partitioned and “measured” as CDPs, DSPs, and standardized plumbing like OpenRTB, Open Measurement, and privacy-preserving APIs expand in parallel, even as publishers race to publish ads.txt and sellers.json and everyone argues about whether 50 percent viewability for one second (or two consecutive seconds for video) counts as truly seeing the ads.

Interpretation
Data, Targeting & Performance Interpretation
In a year when everyone claims they are getting smarter with first party data, AI targeting, clean rooms, and better measurement, the numbers still tell the same blunt story: privacy is tightening, attribution is getting harder, but when personalization and targeting work, clicks convert and budgets follow, even if retargeting and programmatic video keep quietly demanding their share of the spend.
