The reason for the downfall is that the investors finally realized that Nintendo doesnt actually own the mobile phenomenon.
[Pokemon Go] is developed and distributed by Niantic, Nintendo said in a statement on Friday.
The Pokemon Company, which is an affiliated company of Nintendo, holds the ownership rights to Pokemon.
It adds that Nintendo only stands to gain 32% of whatever split TPC benefits from Pokemon Go.
In other words, despite Pokemon Gos huge success, the company did not expect any change in profit.
After the huge success of Pokemon Go, it will undoubtedly garner more interest.
