In one embodiment, a first message and a second message are sequentially displayed in the same presentation vehicle. Initially, the first message may be displayed in the presentation vehicle. The second message may replace the first message in the presentation vehicle if the presentation vehicle is about to be closed. Sequentially displaying two messages in the same presentation vehicle minimizes the number of presentation vehicles on a computer screen and provides at least two chances to attract an end-user's attention. It provides end-users with another alternative choice without taking up any more display space. When employed to display advertisements, for example, this provides more value to end-users and enables more advertisers to reach their target audience.
