Context_1 : Cosmic Avenger is a horizontally scrolling shooter arcade game developed and published by Universal Entertainment Corporation and released in 1981. Like Universal's "Lady Bug", "Cosmic Avenger" was not a hit in arcades, but found success and a larger audience as a launch title for the ColecoVision console. It was not ported to other systems. Wes Hupp holds the official record for this game with 117,290 points on November 17, 1982. Context_2 : Walter A. Sheaffer (July 27, 1867 June 19, 1946) was an American inventor and businessman who developed the first commercially successful lever-filling fountain pen and founded the W.A. Sheaffer Pen Company. Context_3 : Orson Welles Commentaries (194546) is an ABC radio series produced and directed by Orson Welles. Featuring commentary by Welles, with reminiscences and readings from literature, the 15-minute weekly program aired Sunday afternoons at 1:15 p.m. ET beginning September 16, 1945. Lear Radio sponsored the program through the end of June 1946 when it failed to find a larger audience. The series was continued by ABC as a sustaining show through October 6, 1946. "Orson Welles Commentaries" was the last of Welles's own radio shows. Context_4 : Gerhard Heilmann (later sometimes spelt "Heilman") (25 June 1859 26 March 1946) was a Danish artist and paleontologist who created artistic depictions of "Archaeopteryx", "Proavis" and other early bird relatives apart from writing "The Origin of Birds", a pioneering and influential account of bird evolution. Heilmann lacked a formal training in science although he studied medicine briefly before shifting to art. His ideas on bird evolution were first written in Danish in the "Dansk Ornitologisk Tidsskrift". Heilmann received little help and often got considerable opposition from Danish professional zoologists of the time and he in turn often made dismissive remarks on the ideas of some of the established scientists of the time. The English edition however reached out to a much larger audience and influenced ideas in bird evolution for nearly half a century. Context_5 : Founded in 1965, Giorno Poetry Systems was an American artist collective, record label, and non-profit organisation founded by poet and performance artist John Giorno with the direct aim to connect poetry and related art forms to a larger audience using innovative ideas, such as communication technology, audiovisual materials and techniques. Context_6 : William Powell "Bill" Lear (June 26, 1902 May 14, 1978) was an American inventor and businessman. He is best known for founding the Lear Jet Corporation, a manufacturer of business jets. He also invented the battery eliminator for the B battery, and developed the 8-track cartridge, an audio tape system. Throughout his career of 46 years, Lear received over 120 patents. Context_7 : Robert C. Switzer, usually known as Bob Switzer, (19 May 1914 20 August 1997) was an American inventor, businessman and environmentalist. Bob was co-inventor of the first black light fluorescent paint along with his brother Joseph Switzer and the inventor of the Magnaglo process for nondestructive flaw-detection in machined parts. The brothers founded the Day-Glo Color Corp. in 1946 to develop and manufacture fluorescent paints, pigments and other products. Context_8 : The Camel News Caravan or Camel Caravan of News was a 15-minute American television news program aired by NBC News from February 14, 1949 to October 26, 1956. Sponsored by the Camel cigarette brand and anchored by John Cameron Swayze, it was the first NBC news program to use NBC filmed news stories rather than movie newsreels. On February 16, 1954, the "Camel News Caravan" became the first news program broadcast in color, making use of 16mm color film. In early 1955, the R.J. Reynolds Tobacco Company, maker of Camel cigarettes, cut back its sponsorship to three days a week. Chrysler's Plymouth division sponsored the other days, and on those days, the program was labelled the "Plymouth News Caravan". The program featured a young Washington correspondent named David Brinkley, and competed against "Douglas Edwards with the News" on rival CBS. With greater resources, the "News Caravan" attracted a larger audience than its CBS competition until 1955.
