System and method for the presentation of alternative content to viewers of video content

According to certain embodiments of the present invention behavioral patterns are utilized in order to calculate a predicted level of interest of viewers in a specific video item at any given moment throughout the length of the video item. More specifically, according to certain embodiments, this calculation allows to identify instances of peaks of high and low interest throughout the length of the video item. This allows predicting the occurrence of critical moments throughout the video item when it is likely that viewers would abandon the video item on one hand, and moments when viewers are most likely absorbed in the currently presented video, on the other hand. This information allows to capture viewers when their interest in the viewed content is low or decreasing, and to synchronize the presentation of alternative content to these instances.
