The British supermarket chain Tesco published an advertisement in
The Sun announcing the successful development of a genetically modified 'whistling carrot.' The ad explained that the carrots had been specially engineered to grow with tapered airholes in their side. When fully cooked, these airholes caused the vegetable to whistle.

Google revealed the secret at the heart of its search technology:
PigeonRank. Clusters of pigeons had apparently been trained to compute the relative values of web pages:
PigeonRank's success relies primarily on the superior trainability of the domestic pigeon (Columba livia) and its unique capacity to recognize objects regardless of spatial orientation… By collecting flocks of pigeons in dense clusters, Google is able to process search queries at speeds superior to traditional search engines, which typically rely on birds of prey, brooding hens or slow-moving waterfowl to do their relevance rankings. When a search query is submitted to Google, it is routed to a data coop where monitors flash result pages at blazing speeds. When a relevant result is observed by one of the pigeons in the cluster, it strikes a rubber-coated steel bar with its beak, which assigns the page a PigeonRank value of one. For each peck, the PigeonRank increases. Those pages receiving the most pecks, are returned at the top of the user's results page with the other results displayed in pecking order.

Virgin Atlantic announced plans to begin advertising via genetically modified butterflies:
According to a study published in Trends in Ecology and Evolution, Dr Antonia Monteiro at SUNY Buffalo is developing a genetic modification method that would allow companies to put markings such as logos on butterflies by scanning their wings with a laser beam. Virgin is confident that butterfly advertising will become a successful and popular new medium for airlines… Virgin executives say they hope to launch the butterfly program by the spring, allowing time for final testing and lasering of the Virgin logo on the butterflies. Virgin hopes to be able to control the flight areas of the butterflies, keeping them within major park and recreational areas, but is still working out specific details."

Maxim magazine printed multiple covers for its April 2002 issue, simultaneously declaring thirteen different American cities (including Detroit, Philadelpia, New York, and Miami) to be the "Greatest City on Earth." Readers in each city received an appropriately targeted issue of the magazine. In addition to the cover, the issue also included two pages listing the benefits of the cover city and disparaging the other cities. For instance, Philadelphia readers were told about their collective toughness and the Ivy League "hotties" at the University of Pennsylvania. However, readers in other cities were told that Philadelphia was merely a "glorified . . . [bathroom] break between New York and Washington, populated by larded pretzel-munchers and 'half-wits' who dress up as the Founding Fathers." However, some of the New York cover issues were "accidentally" sent to Philadelphia, thus revealing the joke.
