IMS is currently using a DVD as an enticement to help bring back ticket buyers that have fallen from the fold. Buy tickets and get a free Indy DVD.
The folks at Infineon (Sears Point) are using a CD in a mailer to pitch the whole season of events (including the IRL race) at that track to potential customers. Pretty nice.
Here's a couple of menu shots from the disc.
Very "high-tech" looking with interactive, informative graphics and video hilighting the specs of the Indycar Series© cars.
Pretty swift, don't ya' think?
