The Japanese company Enix was established as a publisher of home computer games in August 1982, after founder Yasuhiro Fukushima noticed how popular these were in the United States. Fukushima had no programming knowledge and did not employ internal programmers or game designers. Instead, he held a contest for programming hobbyists in order to pool talents and publish selected games, with a ¥1 million award for the top prize (US$5,000). Due to a lack of brand recognition and the unusually high award, few entries were received in the first month; however, after a successful marketing campaign on television and in appliance stores, hobby clubs, and computer and manga magazines promising that the award was real, three hundred entries were received by the end of the "First Game Hobby Program Contest".
