Whether news sources should be italicized or not depends on the writing style and format being used. Different writing styles have different rules for the treatment of news sources, and it is important to follow the rules of the style that you are using.
One of the most widely used writing styles is the Modern Language Association (MLA) style, which is used in academic writing, especially in the humanities. According to MLA style, the names of newspapers, magazines, and other periodicals should be italicized. For example, The New York Times, Time, and National Geographic would be italicized in MLA style.
Another widely used writing style is the American Psychological Association (APA) style, which is used in social sciences, especially in psychology. According to APA style, the names of newspapers, magazines, and other periodicals should be in sentence case and not italicized. For example, The New York Times, Time, and National Geographic would not be italicized in APA style.
The Chicago Manual of Style (CMS) is another widely used writing style that is used in a variety of fields, including history, literature, and the natural sciences. According to CMS style, the names of newspapers, magazines, and other periodicals should be in regular type and not italicized. For example, The New York Times, Time, and National Geographic would not be italicized in CMS style.
It is also worth noting that some news sources, such as online news websites, do not have a traditional print equivalent and may not be addressed by the traditional writing styles. In these cases, it is recommended to use the format and style used by the publication. For example, if the publication uses sentence case and regular type, the source should be formatted in the same manner.
In conclusion, whether news sources should be italicized or not depends on the writing style and format being used. The Modern Language Association (MLA) style requires the names of newspapers, magazines, and other periodicals to be italicized, while the American Psychological Association (APA) and Chicago Manual of Style (CMS) do not require italicization. It is important to follow the rules of the writing style that you are using, and to be consistent in your formatting throughout your writing. Additionally, if a news source does not have a traditional print equivalent, it is recommended to use the format and style used by the publication.
