Let’s paint a picture; a 40-year-old Tom Cruise walks through a shopping mall. Pocket sized cameras lace the walls where they intermittently scan his face.

The use of browser cookies has been common practice with the online tracking industry since it’s creation and will be what many refer to when discussing the subject.The main reason why cookies were created is because at its base level HTTP is stateless, this means that each request a browser makes is completely separate to the last. Cookies allow for information to be stored or accumulated.
DoubleClick is a great example of this. DoubleClick is a company owned by Google that functions as an advertising network for advertisers. The major difference between Adsense and DoubleClick is that DoubleClick functions as a premium service and has significantly higher bars of entry to its sister platform Adsense.
When a user visits a website with DoubleClick adverts a cookie will be left on their device. This cookie will stay on the users device for a time frame set by the advertising network. For advertising cookies this will normally last for a set amount of time in the future. Each time you visit a website with an advert belonging to the same network it will check your machine for the cookie if you have one it will read t otherwise it will create one.
As for DoubleClick cookies the contents will look something similar to the following:

With this data DoubleClick can cross reference the amount of times it has seen the specific user-id and on which websites it has viewed. Information such as IP addresses also allows the advertising network to derive the device’s location.
