Flash mobs that is.
Flash mobs are becoming more and more common as we find how impacting they are on an audience.
PR and marketing professionals are taking advantage of these occurrences which can be identified as is a large group of people who assemble suddenly in a public place, perform an unusual and sometimes pointless act for a brief time, then quickly disperse. These are fun, surprising, and innocent ways of promoting a product or making a point. Flash mobs create a lot of buzz, especially when done on college campuses.
Several flash mobs that many are aware of include the T-mobile flash mob in the London railway station, the 1,000 person Glee flash mob in Seattle, or the American Airlines flash mob with the link to the video here.
This is a great marketing tool, and although some may snuff at the idea of a flash mob as if it was sooooo 2008, flash mobs are still a rarity in smaller cities and just as effective as any billboard with an advertisement.
One flash mob that I absolutely loved is the recycling flash mob in Canada. Although there is no known organization behind the flash mob, the cause is very clear and powerful. Check out this video.
