The Penny Magazine was an illustrated British magazine aimed at the working class, published every Saturday from 31 March 1832 to 31 October 1845.
 Charles Knight created it for the Society for the Diffusion of Useful Knowledge in response to "Chambers's Edinburgh Journal", which started two months earlier.
 Sold for only a penny and illustrated with wood-engravings, it was an expensive enterprise that could only be supported by very large circulation.
 Though initially very successful—with a circulation of 200,000 in the first year—it proved too dry and too Whiggish to appeal to the working-class audience it needed to be financially viable.
 Its competitor—which included a weekly short story—grew more slowly, but lasted much longer.
The chapters of "Nana" are written and illustrated by Ai Yazawa.
 "Nana" premiered in the Japanese manga magazine "Cookie" in 2000 where it ran until June 2009, when the series was put on hiatus because of Yazawa's illness.
 Yazawa returned from hospital in early April 2010, though had not specified when or if she will resume the manga.
 Yazawa published a two-page chapter of "Junko's Room", a side story about a friend of one of the two main characters, in the March 2013 issue of "Cookie".
 This is the first manga she has published since her 2009 illness.
 The chapters have been collected and published in 21 "tankōbon" volumes in Japan by Shueisha.
Sovetish Heymland (Yiddish סאָוועטיש היימלאַנד - "Soviet Homeland") was a Yiddish-language literary magazine published by poet and controversial figure Aron Vergelis in Moscow as a bi-monthly from 1961 to 1965, then as a monthly until 1991.
 With the dissolution of the Soviet Union, the journal no longer received state support.
 In the early 1960s, "Sovetish Heymland" had a circulation of 25,000, the highest ever circulation for a Yiddish-language periodical.
 The circulation fell to 16,000 in 1966; to 10,000 in 1971; to 7,000 in 1978; and to 5,000 in 1985.
 Although the journal's circulation had fallen dramatically, donations solicited from the United States, France and Argentina in the early 1990s enabled Vergelis to continue publishing the journal under the name "Di Yidishe Gas" (Yiddish די יידישע גאַס - "The Jewish Street") from 1993 until his death in July 1999.
Weekend was a long-running Canadian magazine and newspaper supplement.

 In 1951 the "Standard" was relaunched in magazine format as "Weekend Picture Magazine" serving as a newspaper supplement for the "Montreal Star" and eight other local newspapers across Canada.
 Eventually shortening its name to "Weekend", the magazine, printed using the rotogravure process, included features writing, cultural and entertainment reporting, cartoons by Doug Wright, colour advertising and photographs and recipes among other items.
 The magazine began with a circulation of 900,000 and peaked in the 1960s when it was carried in 41 newspapers and had a circulation of 2.5 million, making it the largest circulation magazine in Canada.
