So Fishing Times’s ad department is selling access to the prime Fishing Times readership. But the Data Lords can say, ‘we can show your ad just to Fishing Times readers when they’re on Facebook, or on some meme site, on the Times or TPM or really anywhere.’ Because the Data Lords have the data and they can track and target you. The publication’s role as the gatekeeper to an audience is totally undercut because the folks who control the data and the targeting can follow those readers anywhere and purchase the ads at the lowest price.
