Automatically generating content for presenting in a preview pane for ADS

The user interfaces, methods and systems described herein facilitate user interaction with an ad space by conveying additional advertising content via a preview pane and facilitate automatically generating the content of the preview pane. By way of example, an electronic advertisement is conveyed to a user in an ad space provided by a third party, and a secondary advertisement generating component automatically generates at least part of the content of a secondary advertisement. The secondary advertisement provides content associated with the electronic advertisement and occurs upon receiving a user indication. A context acquiring component also may provide context information to the secondary advertisement generating component to automatically generate at least part of the content of the secondary advertisement. By way of another example, a user is provided with one or more ads from a plurality of different advertisers in a first ad space maintained by an ad space supplier. A user input identifying at least one of the ads from the plurality of different advertisers is received. A second ad space for a supplemental ad having supplemental advertising information relating to the at least one ad identified by the user input is provided. At least part of the supplemental advertising information supplied in the supplemental ad is automatically produced. Contextual information also may be employed to automatically produce at least part of the supplemental advertising information.
