Introduction - What is Tourism?

Since the beginning of time humans have traveled. Food, water, safety or acquisition of resources (trade) were the early travel motivations. But the idea of travel for pleasure or exploration soon emerged. Travel has always depended upon technology to provide the means or mode of travel. The earliest travelers walked or rode domesticated animals. The invention of the wheel and the sail provided new modes of transportation. Each improvement in technology increased individuals' opportunities to travel. As roads were improved and governments stabilized, interest in travel increased for education, sightseeing, and religious purposes. One of the earliest travel guides was written by Pausanias, a Greek, which was a 10 volume Guide to Greece, for Roman tourists in 170 A.D..
Tourism is a collection of activities, services and industries that delivers a travel experience, including transportation, accommodations, eating and drinking establishments, retail shops, entertainment businesses, activity facilities and other hospitality services provided for individuals or groups traveling away from home. The World Tourism Organization (WTO) claims that tourism is currently the worlds largest industry with annual revenues of over $3 trillion dollars. Tourism provides over six million jobs in the United States, making it the country's largest employer.
