What are Magazines?
Often illustrated and published in printed or digital form on a monthly basis, a magazine (also known as a periodical) is a compilation of texts (essays, articles, stories, and poems) (excluding newspapers).
The creation of inexpensive paper, the development of the rotary press and the halftone block, and, most importantly, the introduction of advertisements as a source of revenue all boosted magazine publication in the late 19th and early 20th centuries.
In the latter half of the 20th century, as the Internet expanded, an increasing number of publications began to post online copies of their content. Other kinds of magazines also grew in popularity at this time. E-zines, also referred to as zines, were among them.
