Advertisements may be displayed on electronic devices within a variety of contexts, such as websites and applications, but the amount of information that may be conveyed by small advertisements in a portion of the screen may be limited. One technique for displaying information in a limited space involves a zoomable advertisement, wherein the advertisement displayed in a first zoom state is supplemented with additional information upon transitioning to a second zoom state (e.g., zooming in to visualize small content, and zooming out to visualize content that was out of bounds in the first zoom state.) Moreover, the content visible at the second zoom state may present advertising content targeted with respect to the user and based on one or more user criteria. The system may notify an advertisement tracking server of various events, e.g., upon rendering the targeted content on behalf of the user. |
