Abstract: An example of an information processing system includes a plurality of user terminals and a server capable of communicating with each user terminal. The server transmits a content to the user terminal. The user terminal executes a first program for displaying a content, thereby displaying on a display apparatus the content received from the server. The user terminal stores related image information indicating a related image related to the content. When executing a second program, which is a program that is different from the first program and can be executed in the user terminal, the user terminal displays on the display apparatus an image by changing an image based on the second program, using the related image information.

Abstract: An example of an information processing system includes a hand-held terminal. The hand-held terminal senses sensor information for determining an emotion of a user. The sensor information may be, for example, information of a sound sensed by a microphone, or information of an image captured by a camera. The information processing system determines the emotion of the user on the basis of the sensor information. The hand-held terminal senses the sensor information in a period during which the hand-held terminal is in a standby state. The standby state is, for example, a state in which a display of the hand-held terminal is turned off.

Abstract: An example of an information processing system includes a plurality of user terminals and at least one server capable of communicating with each user terminal. The at least one server stores a content and a transmission condition for the content in association with each other. The at least one server transmits, to the user terminal regarding which the transmission condition is satisfied, the content associated with the satisfied transmission condition. The at least one server acquires viewing information indicating a state of viewing the content in the user terminal, and updates privilege information so as to give, to the user of the user terminal regarding which the viewing information is acquired, a privilege regarding the state indicated by the acquired viewing information.
