What is NOT a characteristic of periodicals?

The characteristic that is not associated with periodicals is that they are primarily used for advertising. Periodicals, which include magazines, journals, and newspapers, are designed to provide a continuous source of information and scholarly content. They are typically published at regular intervals, allowing readers to keep up with recent developments in a particular field or area of interest.

While periodicals may contain advertising, this is not their primary purpose. Instead, they focus on delivering articles, research, and other content that informs or engages readers. The inclusion of professional articles adds depth to the publication, contributing to its value as a resource for information. Additionally, periodicals typically have a fixed publication date, such as weekly, monthly, or quarterly, which signifies their scheduled release to the audience.

Thus, while advertising can be a part of periodicals, it does not define their main characteristic or function.
