The Chevy/Best Buy cross promotion is a fairly simple banner ad on the surface: rolling your cursor over the hot spot area expands the ad to its full size and reveals another clickable link to get more info.
Behind the scenes, however, lies some quite complex programming that tracks many variables, stores the information, and allows the client to deliver targeted results to the advertiser.
Compatibility Warning: Nearly all of the ads in this Internet Advertising section were developed in Flash out of necessity: As you will see, many are quite involved with interactivity, and all have sophisticated back-ends that read and write to databases to track and to deliver information.
