System for outputting a choice recommendation to one or more users based on earlier choices made by them. A data record is made per choice per user, each data record including a representation of the user, a representation of the choice and a representation of any other user involved with that choice, such as other users that watched a program with the user. The data record may include a representation of the user, a representation of the choice and a representation of no more than one other user involved with that choice, where more records are made when more other users are involved. The data record may include a representation of an environment linked to the choice, e.g. of a localization and/or hardware and/or software linked to the choice. The recorded representation of other users involved with the choice, such as other users that watched a program with the user, is used later to compute the choice recommendation. A synthetic set of watching events for a detected group of users may be determined for this purpose, based on the identity of the members of the group and the representation of "watch with" users of the watching event. |
