1. A device for determining potential interests of users that are clients of at least one network operator, the users being associated with profiles defining the interests of the users, the device comprising: a processor; and memory storing instructions that, when executed, cause the device to: analyze at least one profile of at least one user to determine new real interests associated with the at least one profile by determining the consumption of content items of said at least one user that are related to an interest contained in the profile of said at least one user and considering the interest is a new real interest when said determined consumption of the related content items is greater than a chosen threshold; store an identifier representative of a determined new real interest of said at least one user in correspondence with a first date at which it has been considered as a new real interest into the at least one profile of said at least one user; analyze one or more first dates of said at least one user to determine a time ordered sequence of interests preceding a determined new real interest; and compare the determined user interest sequence to at least one other sequence of interests of at least one other user to predict at least one potential future interest for said at least one user, to be introduced into the at least one profile of said at least one user.
