A Brazilian ad agency has built a campaign for Domino's "Pizza" that uses a heat-sensitive coating on rented DVDs; when the disc is played, the heat from the player heats up the coating and causes it to emit a pizza-like odor; the coating also changes appearance and becomes a picture of a pizza with an ad for Domino's.
In partnership with 10 video rental stores in Sao Paulo and Rio de Janeiro, the brand used rented DVDs as media. About 10 discs each of 10 different new release titles such as Argo, 007, Dread And Dark Knight were stamped with thermal ink and flavored varnish, both sensitive to the heat.
While people were watching the movie, the heat of the DVD player affected the disc. When the movie ended and they ejected the disc, they smelled pizza. They also saw pizza: the discs were printed to look like mini pies, and carried the message: "Did you enjoy the movie? The next one will be even better with a hot and delicious Domino's Pizza."
