Earth Day (English Wikipedia)

Garfield, Bob (March 29, 1999). "AD AGE ADVERTISING CENTURY: THE TOP 100 CAMPAIGNS". adage.com. To the careful observer, the values that underpinned the VW ads actually were aligned with many of the values of Earth Day. The Think Small campaign rebutted the industry's preoccupation with conspicuous consumption with what might be termed 'conspicuous frugality.' The ads were dismissive of massive V-8 engines, tailfins, and bushels of chrome. They took pride in high mileage, low maintenance. They viewed cars as transportation, not status symbols.
