A user of a computing device may view an initial content item in a landscape orientation on a display of a computing device. When the user rotates the computing device, supplemental content may be presented in a portrait orientation on the display of the computing device. The supplemental content may include virtually any information in which the user may be interested and/or that is related or similar to the content item. Accordingly, rather than presenting such supplemental content upon an affirmative request or search by the user, the supplemental content is presented to the user automatically when the user rotates the computing device from a landscape position to a portrait position or vice versa.
