1. One or more computer-readable storage media having computer-executable instructions embodied thereon, that when executed, cause a computing device to perform a method of presenting on a search results page a plurality of preview videos that have been algorithmically determined to be most relevant to various informational items and that are played in succession without user intervention, the method comprising: determining from a database a first informational item and a second informational item that have associated preview videos; algorithmically determining a first video associated with the first informational item and a second video associated with the second informational item, wherein the first and the second videos are determined by a ranking system; algorithmically extracting a first important portion of the first video to form a first preview video and a second important portion of the second video to form a second preview video; combining the first preview video and the second preview video into a single video file such that the second preview video is sequentially played after the first preview video has been played; communicating for display on the search results page the first informational item and the second informational item and the single video file that includes at least the first and the second preview videos; determining a first set of related content associated with the first preview video, wherein the first set of related content is different from the first informational item and the first preview video; determining a second set of related content associated with the second preview video, wherein the second set of related content is different from the second informational item and the second preview video; receiving an indication to initiate play of the single video file: and upon receiving the indication to initiate play of the single video file, automatically and sequentially displaying the first set of related content and the second set of related content such that: (1) only one set of related content is displayed at any one time, and (2) the first set of related content is displayed simultaneously with the first preview video and the second set of related content is displayed simultaneously with the second preview video.
