A computerized system for targeted ad insertion receives a program content stream and detects images in the content stream. The system recognizes at least one visual object within the images and matches the recognized visual object to an advertisement that correlates with the recognized visual object. The system may then select an advertisement that advertises, correlates to, is directed to or is otherwise relevant to products or services falling under the theme, topic, category of interest and/or relevant viewer demographic and inserts an identifier of the matched advertisement at an insertion point into the program content stream. This enables playback of the matched advertisement during playback of the program content stream at a time that correlates to the insertion point into the program content stream of the identifier of the matched advertisement.
