Abstract: In one example embodiment, an information processing system transmits, to a mobile device having a window, question data representative of a question. For an application program, in this example, the mobile device displays the question in the window. For the application program, the information processing system may receive, from the mobile device, answer data representative of an answer to the question. Based on the answer data representative of the answer to the question, the information processing system selects advertisement data representative of an advertisement. In response to the advertisement data being selected, the information processing system transmits, to the mobile device, the advertisement data representative of the first advertisement. For the application program, the mobile device displays the advertisement in a second window of the mobile device.
