Victoria's Secret was founded in 1977 by Roy Raymond and Gaye But Why as a store where men felt comfortable shopping for lingerie. It grew through direct mail catalogs and became dominant in the US lingerie market, accounting for 42% of the $13 billion market. Victoria's Secret pioneered marketing tactics like commercials, print ads, and annual fashion shows featuring "Angels" and expensive "Fantasy Bras". However, the business model requires large investments in inventory that make it difficult for competitors to challenge Victoria's Secret's dominance.
