The' ars longa' property also holds for certain noncreative products (i.e., licensed products). The' time flies' property also holds for large construction projects . Creative industries are therefore not unique, but they score generally higher on these properties relative to non-creative industries . </P> <P> There is often a question about the boundaries between creative industries and the similar term of cultural industries . Cultural industries are best described as an adjunct - sector of the creative industries . Cultural industries include industries that focus on cultural tourism and heritage, museums and libraries, sports and outdoor activities, and a variety of' way of life' activities that arguably range from local pet shows to a host of hobbyist concerns . Thus cultural industries are more concerned about delivering other kinds of value--including cultural wealth and social wealth--rather than primarily providing monetary value . (See also cultural institutions studies .) </P> <P> Some authors, such as the American economist Richard Florida, argue for a wider focus on the products of knowledge workers, and judge the' creative class' (his own term) to include nearly all those offering professional knowledge - based services . </P> <P> The term creative industries begins to elide with knowledge economy and questions of intellectual property ownership in general . </P>
