Oreo O’s is available only in South Korea.
Why only in Korea?
It’s all business.
From 1998 to 2007, Kraft and Post had co-branded to produce Oreo O’s. Kraft has Oreo brand name. And POST has Oreo O’s cereal recipe. Then Kraft and Post ended their co-branding. So Post can’t use the name “Oreo” for the cereal.
On the other side, in Korea there is a local company called “Dongsuh Foods” which is licensed to produce Post cereals in Korea. And Kraft has half of Dongsuh Foods stock. So now Dongsuh Foods is the only company who has legal right to produce both Kraft and Post products. Therefore only Korea has Oreo O’s.
