Travel has been declared dead many times through modern history, impossible in the age of rapid transit and all-inclusive vacation packages. But if travel is over, then what is tourism, probably the world’s biggest industry? The chapter locates the roots of modern tourism in the grand tours of the English aristocracy in the eighteenth century and follows it through the explosion of middle-class tourism in the twentieth century. The chapter also ponders the future of travel in the age of globalization and environmental peril.
