There is a famous story, which is about beer and diapers.
One major retailer in the U.S. found that the beer and diaper sales  were correlated.
The reason was that husbands were asked to buy diapers on their way home from work by their wives and they also picked up beer. Therefore, they just relocated beer next to diaper, then it led to the increase of those sales.

These kinds of stories come from data mining. We can deal with greater amount of data today because of the technology development. The data is called Big Data. Without any doubt, you can gain a lot of benefit if you use it properly.

For example, online dating services developed a unique algorithm for matching men and women from the data such as personal characteristics, reactions and communications.
Another example is that retailers analyze sales, pricing, economic, demographic and weather data. Convenience stores in Japan have the system that umbrellas are automatically delivered to the store if big data says it will rain in the afternoon.

Big data is innovation for marketers and will be used in many kinds of industries.

In this post, I will consider the future of big data a little.
For example, I think people will depend on their smartphones more. They know almost everything about holders from big data and will be able to predict their next movement easily.
If it says, “Eat sushi for lunch!”, most people will follow that.
This is because when a TV program said that bananas were really good for health, most people went to buy it  the next day. Why would people not follow smartphone’s advice?
Of course, it’ll be convenient for us but be somewhat boring for me.
