Final answer:
Stealth marketing is a marketing technique where consumers are exposed to marketing messages without being consciously aware of it, often through subtle product placements or viral strategies.
Step-by-step explanation:
Stealth marketing is a guerrilla marketing technique where consumers are unaware that they are being exposed to a marketing message. This approach is designed to be subtle, blending in with the consumer's environment or activities to avoid the appearance of traditional advertising. Examples of stealth marketing can include product placements in movies or television shows where the brand is shown but not actively promoted, or viral campaigns where a product is discussed or used by people without them explicitly mentioning that it is part of a marketing strategy.
