Marketing is going back to utilize the same measurement technologies that were prevalent before digital tracking was ubiquitous, via Media/Market Mix Modeling (MMM): https://en.wikipedia.org/wiki/Marketing_mix_modeling However, now we can process, hold, and model way more data, driving toward way more useful outputs; but, without any of the privacy implications that exist at a user-level.

So, we now use MMM + user-level attribution (Multi-touch Attribution or MTA) as a hybridized modeling effort to provide what is known in the industry as 'Unified Measurement Modeling' in order to provide the most robust look at how marketing is working.
