In the twenty-first century, which is already being identified in the popular literature as the age of globalization, international business is increasingly identified through the global branding of goods and services, increasingly competitive pressures from emergent markets, new firms and rising consumer demands. The industrial classification of aviation as an industry finds it listed in the international market for services. This is a relatively recent categorization, since formal recognition of the scope and size of services generally was only finally obtained when the sector was added as a formal class of business activities to the General Agreement on Tariffs and Trade (GATT) agenda for the Uruguay Round in 1986. The traditional definition of a firm engaged in international trade is that of a commercial entity seeking to expand both its production and markets by setting up operations to do so across the national boundary of another country.
