Periodical literature (also called a periodical publication or simply a periodical) is a published work that appears in a new edition on a regular schedule.
 The most familiar example is the magazine, typically published weekly, monthly, or as a quarterly.
 Newspapers, often published daily or weekly, are, strictly speaking, serials, not periodicals.
 Other examples of periodicals are newsletters, literary magazines (literary journals), academic journals (including scientific journals), science magazines, and yearbooks.
Viva was an adult woman's magazine that premiered in 1973 and ceased publication in 1980.

 Guccione was the editor of "Penthouse", an adult men's magazine, and he wanted to publish a companion title for women.
 "Viva" was essentially an erotic magazine for women, containing articles and fiction delving into women’s fantasies, and exploring their sexuality, reviews of the arts, interviews with known personalities, fashion and beauty, etc.
The Pall Mall Magazine was a monthly British literary magazine published between 1893 and 1914.
 Started by William Waldorf Astor as an offshoot of the "Pall Mall Gazette", the magazine included poetry, short stories, serialized fiction, and general commentaries, along with extensive artwork.
 It was notable in its time as the first British magazine to "publish illustrations in number and finish comparable to those of American periodicals of the same class" much of which was in the late Pre-Raphaelite style.
 It was often compared to the competing publication, "Strand Magazine", and many artists, such as illustrator Sidney Paget and author H. G. Wells, sold freelance work to both.

The "Chicago Ledger" was a story paper published in Chicago, Illinois from 1872 until 1924.
 Put out by the Ledger Company and edited by Samuel H. Williams, the "Ledger" was a boilerplate literary magazine.
 Such periodicals were printed using engraved steel sheets.
 The plates, or casts of them, were then sent out to be printed and inserted into other newspapers.
 "Ledger" subscriptions originally sold for $1 for 52 issues and, by 1879, the paper had a circulation of 10,000.
 Although begun as a literary paper of "a good class," the "Ledger" eventually became more melodramatic in tone.
 In his 1910 book, Newspapers and Periodicals of Illinois, Franklin Scott, notes that "[t]he sensational, although not immoral, character of the Ledger stories, and the use that the large mail-order houses have made of its advertising columns, have given this paper an unusually long life and extensive circulation."
Ainslee's Magazine was an American literary periodical published from 1897 to December 1926.
