What each tracking service did on your computer

Counted in the browser that loaded this page, before any interaction: 58 tracking services ran 28 scripts, made 190 requests in total and set 124 cookies (122 that stay after you close the browser). We see that these things happened, not what was sent or what the service does with it afterwards. What these mean.
