A Flash Mob Is a Sudden Assembly of Strangers in a Public

A flash mob is a sudden assembly of strangers in a public place for the purpose of performing some novel action (clapping for no reason, singing a song together, dancing, etc.) and then rapidly dispersing. Although they appear to be spontaneous to outsiders, in reality flash mobs are organized through e-mails, social networking sites, and text messages. This is a good example of how technology can:

A) shift recreation to the private sphere.
B) concentrate media power.
C) promote self-regulation and censorship in the media.
D) make it easier to organize people.
E) commodify recreation and leisure.
