Skype Expandable Connection Hub


When a user selects a contact from their contact list to open the Connection Hub, a 728x90 appears in a collapsed state at the top of the Connection Hub screen (above contact information and call options). The user may click the expand button to initiate the panel expansion. The 728x90 pushes content down (no over the page) to 728x315 in size. The ad may contain user initiated video, sound and other interactivity. The user may collapse the ad to its original size by clicking the “Close X” button. All audio and video stops and the screen returns to its load state.
