We partnered with Google for a first of its kind application of Google Maps powering the interactive ad. People could enter their address and pull up a picture of their house from Google Maps. Then they could drag the solar array on to their roof to see how it would look. The media buy for the banner is long over, but the video case study above gives a pretty nice overview of it worked.
