At breakfast and dinner I have the opportunity to watch some Japanese TV with my host family. Often we watch the news, but sometimes we watch one of the many variety shows that are some mix between American game shows and reality shows. Every once in a while they would invite the viewers at home to vote on some topic and 4 primary-colored boxes would appear. I noticed that those colors were lined up in the same order on the TV remote. It apparently costs extra to activate, but this voting system is built into just about every Japanese TV set.
