Some of the Most Popular Websites Share Your Data With Over 1,500 Companies


Cookie pop-ups now show the number of “partners” that websites may share data with. Here's how many of these third-party companies may get your data from some of the most popular sites online.

The newspaper The Daily Mail lists 1,207 partners, while internet speed monitoring firm Speedtest.net, online medical publisher WebMD, and media outlets Reuters, ESPN, and BuzzFeed all state they can share data with 809 companies. “You can always assume all of them are first going to try and disambiguate who you are,” says Midas Nouwens, an associate professor at Aarhus University in Denmark, who has previously built tools to automatically opt-out of tracking by cookie pop-ups and helped with the website analysis. “We have limited insight into, and ability to influence, their operations, terms of business or the partners they choose to work with,” Evans says, also pointing toward Google’s long-running aim to remove third-party cookies from its Chrome browser later this year.
