The most famous event I know is the "rain watching" marketing case of the famous Japanese company Citizen. It has been widely circulated so far. It is said that after this incident, its watch industry made a monthly profit of 2 billion yen in Australia. The specific incident is that Citizen Watch announced in the local mainstream media and newspapers that "one day a watch will be airdropped by helicopter in a square in downtown Australia, and whoever finds it will belong to it", which caused widespread discussion in the local area and created public opinion momentum to attract attention in advance. Secondly, when thousands of people gathered in the square that day, the citizen team scattered thousands of watches from the helicopter to the ground. Everyone witnessed the watch fall to the ground intact. While stunning four seats, it also made "Citizen Watch" famous in World War I ... This kind of "looking at the sky" way with wide brain holes is said today.
