Determining interest in promotional content to be displayed at a mobile communication device is described. The promotional content, including a first portion that is visible and a second portion that is hidden in a first state, may be received. The first and second portions are each selectable only when visible. A promotional display that includes the promotional content in the first state is generated. Upon receipt of a first input from the user in relation to the first portion, the promotional content may be transitioned from the first state to a second state such the first portion becomes hidden and the second portion becomes visible. Upon failing to receive a second input from the user in relation to the second portion, the promotional content may be transitioned from the second state to the first state. Upon receipt of the second input, an interest in the promotional content may be indicated.
