Stealth marketing, also known as undercover or guerrilla marketing, is a subtle and strategic approach to promoting a product or service without the audience realizing they are being marketed to. This form of marketing relies on creating a buzz or word-of-mouth through unconventional and often unexpected methods, such as product placements in movies or TV shows, viral campaigns on social media, or influencer partnerships. The goal of stealth marketing is to create a sense of authenticity and organic interest in the product, rather than overtly pushing it onto consumers. This can be a powerful tool for brands to reach a wider audience and generate buzz, but it also raises ethical concerns about transparency and manipulation of consumer behavior.
