If you flip on your television, chances are pretty high you'll see a McDonalds ad. For those living in Japan, chances are higher you'll see a mobile phone game commercial. Way higher.
For the month of December, the most common commercial on greater Tokyo television was for mobile game site Gree with 2,800 commercials. Number two was rival gaming site Mobage with 2,000 commercials. Mobage operator DeNA is currently in hot water due to its business practices.
