A magazine is a periodical publication containing a variety of articles, generally financed by advertising and/or purchase by readers.

Magazines are typically published weekly, biweekly, monthly, bimonthly or quarterly, with a date on the cover that is in advance of the date it is actually published. They are often printed in color on coated paper, and are bound with a soft cover.

Magazines fall into two broad categories: consumer magazines and business magazines. In practice, magazines are a subset of serials, periodicals and journals, distinct from those periodicals produced by scientific, artistic, academic or special interest publishers which are subscription-only, more expensive, narrowly limited in circulation, and often have little or no advertising.
