11. A non-transitory computer readable storage medium storing program code for presenting social media content items associated with time-based media events, the program when executed by at least one processor causing the processor to: generate a graph interface element including a set of positions along a time axis, where each position is associated with a different portion of a broadcasted media event, the graph interface element depicting a measure of a plurality of content items that are authored by one or more users of a social networking system and that have been determined to be correlated with the portions of the broadcasted media event associated with the set of positions; generate a movable interface element that enables selection among the set of positions included in the graph interface element; populate a content timeline interface element with the plurality of content items arranged in chronological order, each portion of the content timeline interface element including content items correlated with a different portion of the broadcasted media event; provide a concurrent display of the content timeline interface element, the graph interface element, and the movable interface element; determine selection of a first of the set of positions based on the movable interface element having been visually moved to select the first position; and in response to the selection of the first position, cause the provided content timeline interface element to vertically scroll to a first portion of the content timeline interface element that includes content items correlated with a first portion of the broadcasted media event associated with the selected first position; extract non-textual content from a plurality of the content items correlated with the first portion of the broadcasted media event; combine the extracted non-textual content to generate a vignette representing the first portion of the broadcasted media event; and include the vignette in a visually distinct portion of the concurrent display.
