1. A method for the management of a set of parameters for the delivery of spontaneous contents to a user of a terminal comprising: delivering at least one content to the user; detecting whether the user generates on his/her terminal a reaction that is favorable or otherwise to the content delivered; within the set of parameters for delivery of the spontaneous contents, storing to memory at least one parameter representing the said reaction on the part of the user, and at least one contextual parameter associated to the said content delivered so as to adapt the said set of parameters; establishing a schedule via the terminal to deliver at least one spontaneous content selected based on the said adapted set of parameters so as to determine an appropriate moment to deliver the said selected content; and inhibiting the identification of the moment for the delivery of the spontaneous content for a predefined time interval; wherein the powering up of the terminal is monitored, in order to identify at least one moment to deliver the spontaneous content.
