Transit advertising - the Chicago airport

I find non-traditional advertising particularly interesting. Toss together transit advertising (anything displayed in places of transit - e.g., airport, bus station, etc.) with the olympics and you've got an interesting combination. The Chicago airport has consistent messages across all united terminals saying that they are the carrier of US olympians. These ads are found hanging from the airport ceiling, on active billboards throughout the airport, on the sides of moving walkways, and in many other locations as well. Quite interesting given the fact that the olympics ended now several weeks ago.

Transit advertising can be very effective when you have a captive, interested audience. However, companies should be cautious about a variety of things including timing. After a major event is over, take out the ads and start a new campaign.
