This expanding 300 x 250 rich media ad unit expands to full screen upon user click interaction, taking over the users monitor. When a user clicks on the ad unit, it expands to fill the users desktop where the user can interact with the Full screen ad unit video and other rich media options. Using the Esc key or Clicking on the close button closes the Full Screen ad completely, taking the user back to the original ad unit. This ad unit ensures your ad message grabs the attention of the consumer in a powerful way and gives advertisers more room to showcase their content.
