Google has grown since its creation in mid-1997. While Google’s core function remains as a search engine, it has expanded into many other fields. This has been made possible by the way that Google analyzes different sets of data.
The culmination of this effort has resulted in a service called Google Now. With Google Now, it’s possible for Google to provide real-time information that can benefit an individual. For example, Google Now can scan an individual’s mailbox to see if it can provide relevant information in the future. If Google sees that a person’s friend will be arriving on a flight one day, Google Now can display that information to a user quickly and easily through flight tracking.
