Types of Cookies Used on the Digital Media

Necessary cookies: these are essential in order to enable you to move around the Digital Media and use its features, such as accessing secure areas of the Digital Media.

Targeting cookies: these are used to deliver adverts more relevant to you and your interests. They are also used to limit the number of times you see an advertisement as well as help measure the effectiveness of the advertising campaign.
