Science Monthly. The October 1915 issue was titled Popular Science Monthly and World's Advance. The volume number (Vol. 87, No. 4) was that of Popular Science but the content was that of World's Advance. The new editor was Waldemar Kaempffert, a former editor of Scientific American. The change in Popular Science Monthly was dramatic. The old version was a scholarly journal that had eight to ten articles in a 100-page issue. There would be ten to twenty photographs or illustrations. The new version had hundreds of short, easy to read articles with hundreds of illustrations. Editor Kaempffert was writing for "the home craftsman and hobbyist who wanted to know something about the world of science." The circulation doubled in the first year. From the mid-1930s to the 1960s, the magazine featured fictional stories of Gus Wilson's Model Garage, centered on car problems. An annual review of changes to the new model year cars ran in 1940 and 1941, but did not return after the war until 1954. It continued until the mid-1970s when the magazine reverted to publishing the new models over multiple issues as information became available. From 1935 to 1949, the magazine sponsored a series of short films, produced by Jerry Fairbanks and released by Paramount Pictures. From July 1952 to December 1989, Popular Science carried Roy Doty's Wordless Workshop as a regular feature. From July 1969 to May 1989, the cover and table of contents carried the subtitle, "The What's New Magazine." The cover removed the subtitle the following month and the contents page removed it in February 1990. In 1983, the magazine introduced a new logo using the ITC Avant Garde font, which it used until late 1995. Within the next 11 years, its font changed four times (in 1995, 1997, 2001, and 2002, respectively). In 2009, the magazine used a new font for its logo, which was used until the January 2014 issue. In 2014, Popular Science sported a new look and introduced a new logo for the first time in eight years, complete with a major overhaul of its articles. Recent history The Popular Science Publishing Company, which the magazine bears its name, was acquired in 1967 by the Los Angeles-based Times Mirror Company. In 2000, Times Mirror merged with the Chicago-based Tribune Company, which then sold the Times Mirror magazines to Time Inc. (then a subsidiary of Time Warner) the following year. On
