Printed collection of texts (essays, articles, stories, poems), often illustrated, that is produced at regular intervals. Modern magazines have roots in early printed pamphlets, broadsides, chapbooks, and almanacs. One of the first magazines was the German Erbauliche Monaths-Unterredungen (Edifying Monthly Discussions), issued from 1663 to 1668. In the early 18th century Joseph Addison and Richard Steele brought out the influential periodicals The Tatler and The Spectator; other critical reviews began in the mid 1700s. By the 19th century, magazines catering to specialized audiences had developed, including the women's weekly, the religious and missionary review, and the illustrated magazine. One of the greatest benefits to magazine publishing in the late 19th and early 20th centuries was the addition of advertisements as a means of financial support. Subsequent developments included more illustrations and vastly greater specialization. With the computer age, magazines (e-zines) also became available over the Internet.
