Abstract

An information distribution system includes an image display apparatus including a position identification section that identifies the position of the image display apparatus, a first communication section, and a control section; and an information processing apparatus including a storage section that stores content information, a second communication section, and a selection section. The selection section selects at least two contents from a plurality of contents stored in the storage section based on the received position of the image display apparatus. The second communication section distributes content information on the selected at least two contents to the first communication section. The control section sets one content in the received content information as a first content and causes the image display section to display the set first content and the contents other than the first content in the distributed content information in different display forms.
