Flash mob
form of assembling humans

A flash mob (or flashmob) is a group of people that assembles suddenly in a public place, performs for a brief time, then quickly disperses, often for the purposes of entertainment, satire, and/or artistic expression. Flash mobs may be organized via telecommunications, social media, or viral emails.
The term, coined in 2003, is generally not applied to events and performances organized for the purposes of politics (such as protests), commercial advertisement, publicity stunts that involve public relation firms, or paid professionals. In these cases of a planned purpose for the social activity in question, the term smart mobs is often applied instead.
The term "flash rob" or "flash mob robberies", a reference to the way flash mobs assemble, has been used to describe a number of robberies and assaults perpetrated suddenly by groups of teenage youth. Bill Wasik, originator of the first flash mobs, and a number of other commentators have questioned or objected to the usage of "flash mob" to describe criminal acts. Flash mobs have also been featured in some Hollywood movie series, such as Step Up.
History
First flash mob
The first flash mobs were created in Manhattan in 2003, by Bill Wasik, senior editor of Harper's Magazine. The first attempt was unsuccessful after the targeted retail store was tipped off about the plan for people to gather. Wasik avoided such problems during the first successful flash mob, which occurred on June 17, 2003, at Macy's department store, by sending participants to preliminary staging areas—in four Manhattan bars—where they received further instructions about the ultimate event and location just before the event began.

Why this record matters
“Flash mob” is worth following because a concise public description often conceals a longer documentary argument. Here, Flash, form and assembling provides the most credible route into that argument.
Named sources, stable identifiers and responsible institutions provide the strongest route from overview to verifiable evidence. The source revision retrieved here is dated Aug 14, 2026. The linked authority identifier is Q152263. None of the 0 selected statements returned an explicit reference. The first chronological checks are 2003.
A concise general-reference account can conceal disagreements about scope, terminology or the weight assigned to individual sources. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
