Propaganda copy has a strong purpose and utility. In order to attract more attention to your own products or activities, and ultimately maximize the advertising effect, it takes a lot of effort to make a copy, whether it is material, human or financial. The difference lies in a number problem.
With regard to copying copywriting, a lot of plagiarism means copying the creativity and layout of copywriting, and then replacing the other party's pictures with their own activities or products, and appropriately modifying the text content to serve the creativity of others.
Copywriting plagiarism is difficult to define, because copywriting is used in a small scope after it is made, and it is difficult to find it unless it appears in the same place at the same time. Copywriting plagiarism can also be seen in posters and printed materials on DM sheets. Because of innovation, although we can see the shadow of plagiarism, defining it is a troublesome thing.
