Marketing history of olfactory marketing

Perfume marketing may be as old as word of mouth, or even longer. Since ancient times, vendors in open-air markets have attracted passers-by to their stalls by burning incense.

In 2002, Coca-Cola launched Lemon Cola in Shanghai. Coca-Cola put a perfume into a machine with automatic sensing function and put it in a telephone booth at a bus stop. When people pass by, the taste sensor will automatically emit fragrance, which has been reported in major newspapers. McDonald's later adopted this advertising form in Beijing. At breakfast time, as long as someone approaches the billboard in the bus shelter, the billboard will automatically play the sound advertisement of McDonald's breakfast and send out a fragrance.

NTT developed a device that can generate fragrance synchronously with the content of digital TV programs, which was well received at the "Digital Technology 2005" Expo held in March 2005. In the 3-minute cooking program demonstrated on the spot, the aroma generator adjusts the appearance time and intensity of seven kinds of smells such as beef, tomato, oyster, black pepper, garlic, roasted garlic and oyster sauce according to the images of beef, leek and oyster. At the beginning, it gives off the smells of various food raw materials and seasonings. With the cooking process, it gives off mixed smells, and the intensity of each smell is divided into 10.

On February 5th, June 5438, 2006, California Milk Processing Board issued a notice "Did you drink milk?" Our advertisement can give passers-by an attractive smell of freshly baked chocolate biscuits. Special balsam was applied to the interlayer of the bus shelter, and the fragrance was close to 100% truth.
