During the second half of the twentieth century, in a world transformed by international tensions, the centre of artistic creation shifted from Europe to the United States. In a world where major countries asserted their power, individualism now ruled. The art world was a perfect example of this phenomenon; even now, the emphasis of creativity is placed on the individual instead of the trend. Moreover, growing globalization and the various types of media have facilitated a multiplication of means and offered artists new possibilities. Now, at the dawn of the twenty-first century, everything has the potential to be art, and art, more than ever, is the opportunity to take risks - to present and transform almost anything. This work invites the reader to discover the diversity of this most recent artistic environment.
