Postmodernism emerged after modernism in the mid-20th century. It is characterized by mixing different artistic styles and media and being influenced by pop culture and media texts that dominate reality. Postmodernism differs from modernism in that modernism was influenced by new technologies from 1890-1945 and artists had to stick to traditions, whereas postmodernism allows for more freedom of expression and mixing of styles as it is a response to modernism running out of new ideas after 100 years.
