1. A contents'"'"' relationship visualizing apparatus comprising:
- at least one memory storing instructions; and
at least one processor programmed via the instructions to;
acquire a usage history comprising, for each one of a plurality of items of content, a user set comprising a plurality of elements each corresponding to a user who has utilized the one item of content;
compare the plurality of elements in each user set to identify a set of elements common to each user set;
calculate a similarity between the user sets by comparing the elements common to each user set to at least one of a total number of elements in at least one user set, a minimum number of elements contained in each user set, and a distance between the user sets;
generate information representing a network, the network indicating one or more relationships between the plurality of items of content along a time-line comprising a plurality of usage time periods, the one or more relationships being based at least in part on the calculated similarity between the user sets.

12. A contents'"'"' relationship visualizing method, the method comprising:
-
determining, using at least one processor, a usage history comprising, for each one of a plurality of items of content, a user set comprising a plurality of elements each corresponding to a user who has utilized the one item of content; comparing, using the at least one processor, the plurality of elements in each user set to identify a set of elements common to each user set; calculating, using the at least one processor, a similarity between the user sets by comparing the elements common to each user set to at least one of a total number of elements in at least one user set, a minimum number of elements contained in each user set, and a distance between the user sets; and generating, using the at least processor, information representing a network, the network indicating one or more relationships between the plurality of items of content along a time-line comprising a plurality of usage time periods, the one or more relationships being based at least in part on the calculated similarity between the user sets; and providing the generated information to a device configured to visually display the network.
