In past, TV program about health and food was very popular in Japan. It was aired from 1996 to 2007. The program showed how certain food (for example, Natto) is benefical to one’s health through some experiments. It is said that the program contributed to health fad in Japan.

Here is an example that shows the TV program had strong influence on purchasing.

My friend was working in convenience store like Seven Eleven.

He told me.

The shop manager always checked what foods would be covered next week in advance notice. One day, It was a yogurt. He ordered a yougurt in volume and arranged to get the shipment at mid-night of the TV show because many people who watch the TV show would come and buy the prodoct. The products were sold well.

Last year it was revealed that the TV program showed some falsified data. It was a big problem. The famous academic magazine “Nature” took this topic and the problem of the program gained topicality in the world.

What is the truth? It is difficult for people to make sure of a fact about things TV shows take. What should we believe in media? What do we watch TV for?
