Like the conference business, the exhibition industry appears to be growing. Between 1994 and 1998 the European industry, as indicated by exhibitor participation, was growing by over 4 per cent a year. In Germany, the modern Messe (会展中心) of Germany evolved at the beginning of the century from the centuries-old trade fairs. The Germans have maintained their lead through the development of specialist trade fairs as well as the continued development of their facilities. Their strength is not in the number of shows, but in their large size and international character. Germany is, of course, an important industrial country and it could be expected that there would be some correlation between exhibitions and industrial development. Frequently, as in Detroit in the USA, there is a link between trade fairs and the industries which are important in the local region.

Since the 1990s, computer technology has been more widely applied to tourism in China where it has brought increasing economic benefit. Some large travel agencies are promoting the use of computers and the Internet in their operations, management and overseas promotion. China International Travel Service(CITS), the first to use computer management in China's tourism industry, has installed computers of various types to sell tourist products, quote prices, make reservations, work out schedule, arrange various services, settle tourist accounts and other financial matters. CITS China information goes out via Australia's Worldlink to more than 250,000 computer terminals worldwide.
