AdTech covers the technology layer underneath advertising: demand and supply platforms, measurement and attribution, identity and consent, retail media, connected TV inventory and the fast growing set of AI-native ad tools. It reports what the platforms ship, what agencies adopt and what the performance data shows, rather than the creative work itself. The section is new. It opened in June 2025 and has already passed two hundred pieces, which is a fair measure of how quickly AI is rebuilding this part of the market.
