In the broadest sense, the word art denotes any developed activity of human beings based on knowledge, practice, perception, imagination and intuition (the art of healing, the art of free speech). According to Tasos Zembylas, the process of formation of the concept of art is subject to constant change, unfolding along dynamic discourses, practices and institutional instances.
Art is a human cultural product, the result of a creative process. The artwork is usually at the end of this process, but it can also be the process or procedure itself. Like art as a whole, the work of art itself is characterized by the interaction of content and form. Practitioners of art in the narrower sense are called artists.
Forms of expression and techniques of art have expanded greatly since the beginning of modernity, for example with photography in the visual arts or with the establishment of comics as a combination of visual art with the narrativity of literature. In the case of the performing arts, music and literature, forms of expression of the new media such as radio, television, advertising and the Internet can also be added today. The classical classification has been losing importance since the last decades of the 20th century at the latest. Art genres such as installation or the field of media art no longer recognize the classic basic classification.
