Abstract: This disclosure relates to displaying notifications for content items on a mobile device to a user. A processor receives meta-data associated with the content item and receives context data indicative of a current context of the mobile device. The processor then determines a first value based on the meta-data, the context data and historical data indicative of historical interactions with historical notifications that are based on the meta-data, the first value being indicative of a current likelihood of the user interacting with a notification that is based on the meta-data. Finally, the processor sends first output data based on the first value to an output module to allow selectively outputting the notification based on the current likelihood. By selectively outputting the notification based on the current likelihood the notification can be withheld until the user is likely to interact with the notification.

Abstract: This disclosure relates to selectively playing a video on a mobile communication device. The device monitors events and upon detecting a trigger event, determines whether to delay the playing of a first video or to attempt to play the first video. Upon determining to delay, the device stores a delay record. The device repeats the above steps to generate multiple delay records. Upon determining to attempt to play the first video, the device displays a user control to allow the user to reject the first video and stores an attempt record. Upon detecting user interaction with the user control element, the device calculates a relationship between the delay records, the attempt record, and the user interaction with the user control element. This allows the device to determine whether to delay the playing of a second video or to play the second video. Upon determining to play the second video, the device plays the second video.
