Ch. 1 - Overview of Marketing (Brief History and Mission Statement)

Before Square Enix became what it was today, it started as two different gaming companies. these two companies were Enix and Square. Originally, Enix was named Eidansha Boshu Service Centre. Founded in 1975, the Eidansha Boshu Service Centre was a branch of Eidansha Systems.  In 1982, Eidansha Boshu Service Centre was renamed Enix. In 1986, Masafumi Miyamoto and Hironobu Sakaguchi founded Square which was a branch of the Denshuya Electric Company.  One of the big hit games made by Enix was Dragon Quest. 

Using Dragon Quest as inspiration, Square created a big hit game in 1987 which is still popular among gamers today. This game was the very first Final Fantasy title that was released. 

In time, sequels were created to the big game franchise. In 2001, the film Final Fantasy: The Spirits Within was released.  This film lost Square 120 million dollars. after losing its financial stability, Sony gave a 14.9 billion dollar contract to Square which led to the merger with Enix. From that day forth, it these two companies were known as Square Enix. 

As for their mission statement, it is; "To spread happiness across the globe by providing unforgettable experiences."
