About this tag
The real time bidding tag on WindowsForum.com collects discussion of programmatic ad auctions and the platforms behind them, including Microsoft Advertising and its Xandr ad-tech unit. Coverage here focuses on how real time bidding systems handle personal data, the regulatory consequences when they do not, and what such enforcement means for Microsoft's advertising stack.

Expect thread-level analysis rather than vendor marketing, useful to readers tracking ad-tech compliance and Microsoft's role in it.
