Final Answer:
The mobilization of a mass group of individuals by means of communications technology to meet at a moment's notice for a specific purpose or action is known as:a) Flash mob.
Step-by-step explanation:
A flash mob refers to the mobilization of a large group of individuals through the use of communications technology to assemble quickly for a specific purpose or action. This phenomenon gained prominence with the advent of social media and instant communication platforms.
Participants receive instructions online, organizing impromptu gatherings in public spaces for activities such as dancing, singing, or conveying a message. The term "flash" denotes the sudden and brief nature of these gatherings, often dispersed as quickly as they form.
Flash mobs leverage the power of social connectivity, relying on the swift dissemination of information through digital channels. Participants, often strangers, come together temporarily to create a collective and often entertaining spectacle. The spontaneity and unpredictability of flash mobs contribute to their appeal, making them a unique form of social expression and a means of drawing attention to various causes or messages. This phenomenon showcases the influence of modern communication technologies in facilitating rapid, large-scale coordination among individuals for shared experiences or activism.
