McM

MCM is an acronym that can refer to several different concepts depending on the context, and there is no single meaning universally associated with the term.

In electronics, MCM stands for Multi-Chip Module, a packaging technology that consolidates several integrated circuit dies on a single substrate or module. This approach reduces footprint and can improve performance by shortening interconnect lengths between chips, and it is used in various high-density applications such as computer and communications hardware.

In marketing, MCM stands for Multi-Channel Marketing, a strategy that engages customers across multiple channels—digital, print, retail, events—to create a cohesive, cross-channel customer experience. It is often discussed in contrast with single-channel approaches and can be complemented by omnichannel practices to ensure consistency across touchpoints.

In popular culture, MCM is commonly used as the abbreviation for Man Crush Monday, a social media tag used to highlight a male crush on Mondays. It is widely seen on platforms such as Instagram and Twitter and forms part of informal online etiquette and memes.

In fashion and luxury branding, MCM refers to Mode Creation Munich, a German luxury fashion brand established in 1976 in Munich. The brand is known for its leather goods and accessories, and for using the MCM initials as its logo, often paired with a laurel motif.
