Twin Galaxies
On July 25, 1983, Twin Galaxies established the professional U.S. National Video Game Team, the first such, with Walter Day as team captain. The USNVGT toured the United States during the summer of 1983 in a 44-foot GMC bus filled with arcade games, appearing at arcades around the nation and conducting the 1983 Video Game Masters Tournament, the results of which were published in the 1984 U.S. edition of "Guinness World Records". Under the direction of Day, functioning as an assistant editor for the "Guinness Book" in charge of video-game scores, the USNVGT gathered annual contest results that were published in the 1984—1986 U.S. editions. In September 1983, the USNVGT visited the Italian and Japanese Embassies in Washington D.C. to issue challenges for an international video game championship. In 1987, the USNVGT toured Europe where it defeated a team of UK video game superstars. Every month between 1991 and 1994, the U.S. publication "Electronic Gaming Monthly" ("EGM"), published a full-page high-score table titled "The U.S. National Video Game Team's International Scoreboard".
