masshow

Masshow is a term used to describe large-scale, orchestrated public performances in which participants are guided to perform synchronized actions. These events are typically coordinated through digital media, messaging apps, or live cues and can be designed for entertainment, marketing, social research, or political expression. The concept draws on earlier forms such as flash mobs but tends to imply a higher level of planning, staging, and content control.

Origins and usage of the term are varied and not uniformly standardized. Masshow has appeared in journalism, event-planning literature, and discussions of crowd-based art and activism since the early 21st century. In some contexts, it is used interchangeably with related ideas like mass participation performances or participatory public art; in others, it denotes a more deliberate, choreographed show rather than a spontaneous gathering.

Key features commonly associated with masshow include careful planning and logistics, the use of cues delivered via mobile apps or social media, and the involvement of a core organizing team that designs the sequence of actions and ensures timing. These events can range from dozens to thousands of participants and may be staged in urban spaces, campuses, or festival settings. Content and theme are typically devised to maximize visual impact, participant engagement, and media reach.

Ethical and practical considerations arise with masshow, including safety, legal permissions, consent, accessibility, and the potential for disruption or manipulation. Proponents view masshow as a creative or social experiment, while critics raise concerns about crowd safety and consent.
