Business can refer to a particular organization or to an entire market sector, e.g. the music business. Compound forms such as agribusiness represent subsets of the word's broader meaning, which encompasses all activity by suppliers of goods and services.
What exactly is marketing mix modeling? The term is widely used and applied indiscriminately to a broad range of marketing models used to evaluate different components of marketing plans, such as advertising, promotion, packaging, media weight levels, sales force numbers, etc.
A second reason for the growing interest in marketing mix modeling is the proliferation of new media (i.e., new ways to spend the marketing budget), including the Internet, online communities, search engines, event marketing, sports marketing, viral marketing, cell phones, and text messaging, etc.
