The server is communicably connected to a user terminal via a communication network and provides a live video distribution service for distributing and viewing a live video to the user via the user terminal. The server associates (adds) the tag input by the user who is viewing a live video with this live video and presents information on the live video being distributed based on the associated tag. Therefore, the user can know the current content (topic) of the live video being distributed from the information based on the tag input by the actual viewer. As a result, for example, a new user can comfortably start viewing the live video. ## Claims ### Claim 1 A system comprising one or more computer processors, the one or more computer processors executing machine-readable instructions to perform: presenting information on at least one of a plurality of live videos being distributed to a user; and managing association of tags with the live videos, wherein the managing of the association includes associating a first tag input by a first user viewing a first live video with the first live video; the presenting includes presenting the information based on at least one of the tags in a predetermined state in which an elapsed time after each of the tags has been associated with corresponding one of the live videos is within a first time; the presenting includes presenting a first list of tags respectively associated with the live videos; and the first list is configured so that a tag associated with a larger number of live videos is prioritized. ### Claim 2 (depends on 1) The system according to claim 1, wherein the managing of the association includes limiting the number of tags in the predetermined state that can be associated with one of the live videos. ### Claim 3 (depends on 1) The system according to claim 1, wherein the managing of the association includes limiting the number of tags that can be associated with one of the live videos within a second time. ### Claim 4 (depends on 1) The system according to claim 1, wherein the managing of the association includes limiting the number of tags that can be associated with one of the live videos by one user within a third time. ### Claim 5 (depends on 1) The system according to claim 1, wherein the managing of the association includes limiting an inputter user who can input a tag based on at least an attribute of each of a plurality of users. ### Claim 6 (depends on 5) The system according to claim 5, wherein the managing of the association includes limiting the inputter user who can input the tag to be associated with the first live video to a plurality of certain users who have a predetermined relationship with a distributor user who distributes the first live video. ### Claim 7 (depends on 1) The system according to claim 1, wherein the one or more computer processors further perform receiving a comment input via a viewing screen for viewing a live video; the managing of the association includes receiving a tag input via the viewing screen; and the viewing screen has a predetermined area in which a first character string input in a first state is recognized as the comment and a second character string input in a second state is recognized as the tag. ### Claim 8 (depends on 1) The system according to claim 1, wherein the presenting includes presenting a second list of live videos based on at least a tag associated with each of the live videos. ### Claim 9 (depends on 8) The system according to claim 8, wherein the presenting includes presenting the second list in which at least one of the tags respectively associated with the live videos is arranged in chronological order together with a corresponding live video. ### Claim 10 (depends on 8) The system according to claim 8, wherein the second list is a list of the live videos each of which is associated with a specific tag. ### Claim 11 A system comprising one or more computer processors, the one or more computer processors executing machine-readable instructions to perform: presenting information on at least one of a plurality of live videos being distributed to a user; and managing association of tags with the live videos, wherein the managing of the association includes associating a first tag input by a first user viewing a first live video with the first live video; the presenting includes: presenting the information based on at least one of the tags in a predetermined state in which an elapsed time after each of the tags has been associated with corresponding one of the live videos is within a first time, and presenting a second list of live videos based on at least a tag associated with each of the live videos; and the one or more computer processors further perform displaying a predetermined notification regarding a second tag corresponding to a second live video in the second list on a viewing screen for viewing the second live video when a second user starts viewing the second live video via the second list. ### Claim 12 (depends on 11) The system according to claim 11, wherein the predetermined notification includes a notification regarding the second user's start of viewing via the second tag. ### Claim 13 (depends on 11) The system according to claim 11, wherein the predetermined notification includes a notification regarding a third user who associates the second tag with the second live video. ### Claim 14 (depends on 8) The system according to claim 8, wherein the one or more computer processors further perform increasing a value of a predetermined parameter of a third user who associates a second tag corresponding to the second live video in the second list when the second user starts viewing the second live video via the second list. ### Claim 15 (depends on 1) The system according to claim 1, wherein the managing of the association includes automatically posting, to a predetermined SNS, a posting content including the first tag and introducing the first live video when the first tag is associated with the first live video. ### Claim 16 (depends on 1) The system according to claim 1, wherein the managing of the association includes associating the first tag with a distributor user who distributes the first live video in addition to the first live video. ### Claim 17 A non-transitory computer-readable medium including a program, the program causing one or more computers to execute: presenting information on at least one of a plurality of live videos being distributed to a user; and managing association of tags with the live videos, wherein the managing of the association includes associating a first tag input by a first user viewing a first live video with the first live video; the presenting includes presenting the information based on at least one of the tags in a predetermined state in which an elapsed time after each of the tags has been associated with corresponding one of the live videos is within a first time; the presenting includes presenting a first list of tags respectively associated with the live videos; and the first list is configured so that a tag associated with a larger number of live videos is prioritized. ### Claim 18 A non-transitory computer-readable medium including a program, the program causing one or more computers to execute: presenting information on at least one of a plurality of live videos being distributed to a user; and managing association of tags with the live videos, wherein the managing of the association includes associating a first tag input by a first user viewing a first live video with the first live video; the presenting includes: presenting the information based on at least one of the tags in a predetermined state in which an elapsed time after each of the tags has been associated with corresponding one of the live videos is within a first time, and presenting a second list of live videos based on at least a tag associated with each of the live videos; and the one or more computers further execute displaying a predetermined notification regarding a second tag corresponding to a second live video in the second list on a viewing screen for viewing the second live video when a second user starts viewing the second live video via the second list.
