A method (300) and system (100,200) for customizing a user interface (122) on a display or consumption device (121) is provided. In one embodiment, the method includes delivering, with a control circuit (210), an advertisement (114) to a plurality of client devices (106,107,108). A channel collector device 113 can then capture viewership activity data (116,117,118) occurring during playout of the advertisement. The method then modifies a presentation characteristic of the user interface by presenting a playback (501) comprising both the advertisement and at least some of the viewership activity data in synchrony.
