''Popular Electronics'' was an American magazine started by Ziff-Davis Publishing in October 1954 for electronics hobbyists and experimenters. It soon became the "World's Largest-Selling Electronics Magazine". The circulation was 240,151 in April 1957 and 400,000 by 1963.〔The early issues listed the circulation figure on the Contents page. Starting in 1962 this data was in the back of each years January issue. The circulation was around 400,000 until 1985.〕 Ziff-Davis published ''Popular Electronics'' until April 1985. The title was sold to Gernsback Publications, and their ''Hands-On Electronics'' magazine was renamed to ''Popular Electronics'' in February 1989, and published until December 1999. A cover story on ''Popular Electronics'' could launch a new product or company. The most famous issue, January 1975, had the Altair 8800 computer on the cover and ignited the home computer revolution. Paul Allen showed that issue to Bill Gates. They wrote a BASIC interpreter for the Altair computer and started Microsoft.〔(【引用サイトリンク】 publisher = New Mexico Museum of Natural History and Science )〕 ==How it started== ''Radio & Television News'' was a magazine for professionals and the editors wanted to create a magazine for hobbyists. Ziff-Davis had started ''Popular Aviation'' in 1927 and ''Popular Photography'' in 1934 but found that Gernsback Publications had the trademark on Popular Electronics. It was used in ''Radio-Craft'' from 1943 until 1948. Ziff-Davis bought the trademark and started ''Popular Electronics'' with the October 1954 issue. Many of the editors and authors worked for both Ziff-Davis magazines. Initially Oliver Read was the editor of both ''Radio & Television News'' and ''Popular Electronics''. Read was promoted to Publisher in June 1956. Oliver Perry Ferrell took over as editor of ''Popular Electronics'' and William A. Stocklin became editor of ''Radio & Television News''. In ''Radio & TV News ''John T. Frye wrote a column on a fictional repair shop where the proprietor, Mac, would interact with other technicians and customers. The reader would learn repair techniques for servicing radios and TVs. In ''Popular Electronics'' his column was about two high school boys, Carl and Jerry. Each month the boys would have an adventure that would teach the reader about electronics. By 1954 building audio and radio kits was a growing pastime. Heathkit and many others offered kits that included all of the parts with detailed instructions. The premier cover shows the assembly of a Heathkit A-7B audio amplifier. ''Popular Electronics'' would offer projects that were built from scratch; that is, the individual parts were purchased at a local electronics store or by mail order. The early issues often showed these as father and son projects. Most of the early projects used vacuum tubes, as transistors (which had just become available to hobbyists) were expensive: the small-signal Raytheon CK722 transistor was US$3.50 in the December 1954 issue, while a typical small-signal vacuum tube (the 12AX7) was $0.61. Lou Garner wrote the feature story for the first issue, a battery powered tube radio that could be used on a bicycle. Later he was given a column called Transistor Topics (June 1956). Transistors soon cost less than a dollar and transistor projects became common in every issue of ''Popular Electronics''. The column was renamed to Solid State in 1965 and ran under his byline until December 1978. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Popular Electronics」の詳細全文を読む スポンサード リンク
