Tourism
Tourism is the act of travel for the purpose of recreation and business, and the provision of services for this act. Tourists are people who are "travelling to and staying in places outside their usual environment for not more than one consecutive year for leisure, business and other purposes not related to the exercise of an activity remunerated from within the place visited" (official UNWTO definition). The distance between these two places is of no significance.
A more comprehensive definition would be that tourism is a service industry, comprising a number of tangible and intangible components. The tangible elements include transport systems — air, rail, road, water and now, space; hospitality services — accommodation, foods and beverages, tours, souvenirs; and related services such as banking, insurance and safety and security. The intangible elements include: rest and relaxation, culture, escape, adventure, new and different experiences.
Many countries depend heavily upon travel expenditures by foreigners as a source of taxation and as a source of income for the enterprises that sell (export) services to these travellers. Consequently the development of tourism is often a strategy employed either by a Non-governmental organization (NGO) or a governmental agency to promote a particular region for the purpose of increasing commerce through exporting goods and services to non-locals.
Sometimes Tourism and Travel are used interchangeably. In this context travel has a similar definition to tourism, but implies a more purposeful journey.
The terms tourism and tourist are sometimes used pejoratively, implying a shallow interest in the societies and places that the tourist visits
