Information channels are used in different ways and combinations by different people, businesses, and communities. A tourism information system is a specific type of information system. It consists of all the information channels used in a business or community to promote itself as a tourism attraction. These information channels include commercials, ads, brochures, repeat visitors, employees, friends, and relatives. Each channel in the system has its own function.
Travelers use different channels to get different kinds of information.
An example is deciding where to go on vacation. All the information channels used in the system relate to each other. A tourism information system is like a novel because it has many different parts tied together by the theme. Even though a system's channels serve different functions in providing information, they are all tied together by the projected message. All channels used in the system are interdependent.
