Abstract: Providing content in a content list may include identifying positions within the list where content can be provided. A client agent may automatically play items of content at a first position when determining that the first position is within a displayed region of the content list. The client agent may identify a duration during which the first item is within the displayed region of the list, pause playback of the first item at a point in time when the displayed region of the list is advanced to no longer include the first position, and compare the first duration to a threshold value. The client agent may determine that the displayed region of the list has advanced to a second position and resume playback of the first item near the point in time and at the second position if the duration is less than the threshold value.

Abstract: Systems, methods, and apparatus include computer programs encoded on a computer-readable storage medium, including a system for ranking videos. Videos are identified that have been presented at client devices. For each video, session start data is identified that specifies a lead video that initiated presentation to a user during a presentation session. For each lead video, presentation times over multiple user sessions are determined, a scaled presentation time is obtained, user sessions for which the lead video initiated presentation of videos are identified, and an aggregate video presentation time attributable to the lead video is determined. For each given video, a presentation score is determined based on a scaled presentation time of the lead video relative to a sum of the aggregate video presentation times for the lead videos. The videos are ranked based on the presentation scores. A user interface is updated to present the ranked videos.

Abstract: Implementations relate to continuation of playback of media content by different devices. In some implementations, a method includes causing a stream of media content data to be received from a stream source and output by a first device to a user, where a portion of the data is buffered on the first device before output. An indication is detected that the user has stopped using the first device for output of the content data. A place marker indicates a portion of the content that is output approximately at the time of the indication. The method causes the stream of content data to be received and output by a second device starting at the place marker portion. The buffered content data is sent from the first device to the second device for output by the second device before unbuffered portions of the content data received from the stream source.
