The commercial spirit or method.

Commercialism, in its original meaning, is the practices, methods, aims, and spirit of commerce or business. Today, however, it is mainly used as a critical term, referring to the tendency within capitalism to try to turn everything in life into objects and services that are sold for the purpose of generating profit; commercialization, where the value of everything, including such intangible things as happiness, health and beauty become measured in purely commercial, materialistic terms, and where public services are being privatised or outsourced to private companies.
