History of Nintendo
In 1972, the first commercially available video game console, the Magnavox Odyssey, had a light gun accessory, the Shooting Gallery. This was the first involvement of Nintendo in video games. According to Martin Picard in the "International Journal of Computer Game Research": "in 1971, Nintendo had -- even before the marketing of the first home console in the United States -- an alliance with the American pioneer Magnavox to develop and produce optoelectronic guns for the Odyssey (released in 1972), since it was similar to what Nintendo was able to offer in the Japanese toy market in 1970s".
Nintendo Power
Nintendo Power was founded by Nintendo of America marketing manager Gail Tilden in 1988. Predating "Nintendo Power" is the several-page long "Nintendo Fun Club News", which was sent to club members for free. However, in mid-1988 "Nintendo Fun Club News" was discontinued after seven issues in favor of "Nintendo Power". The first issue, dated July/August 1988, spotlighted the NES game "Super Mario Bros. 2". Of this issue, 3.6 million copies were published, with every member of the Nintendo Fun Club receiving a free one.
