Tracker Watch: weekly, passive and reproducible measurement of third-party tracking on news websites

Weekly measurements of the third-party tracking services that 48 news websites (12 from the US, the UK, Germany and Spain) contact before any interaction, with the classification list, the site list and the trends compiled from the series. Counts, not legal conclusions: they come from one origin (GitHub servers in the US), use a limited hand-built classification list and say nothing about intent. The data are under CC BY 4.0; the code in this snapshot of the repository is under the PolyForm Noncommercial License 1.0.0. Method and live site: https://joseasenjo.github.io/tracker-watch/
