Viral Marketing
Viral marketing is an advertising approach where brands rely on consumers to spread promotional content through email, social platforms and word of mouth. The term was coined in the mid-1990s and moved from theory to practice when Hotmail's 1996 signature-tagline experiment drove millions of signups without traditional paid media.
Overview
Viral marketing is an advertising strategy that gets consumers to distribute promotional content themselves, most often through email chains, social platforms and shareable web videos 1. The idea borrows from epidemiology: a successful campaign spreads person to person the way a virus does, letting a brand reach large audiences without paying for each impression 1.
Because the message travels through friend networks rather than paid media buys, viral marketing is usually cheaper than traditional advertising and reads to viewers as entertainment or personal recommendation rather than sales copy 1. The flip side is that the same word-of-mouth mechanic can turn on a brand fast when the audience decides to mock a campaign instead of forward it 1. Since the mid-2000s the word 'viral' itself shifted from niche ad-industry jargon to the default expectation for anything published online 2.

Viral marketing campaigns typically pair a shareable creative hook with a low-friction way for audiences to forward it, plus either overt or hidden brand attribution 1. Common conventions include producing web-native footage designed to feel like entertainment rather than an ad, seeding content on YouTube or social platforms before any paid promotion, and inviting audiences to remix or respond to the material 2.
