England is highly industrialised, but since the 1970s there has been a decline in traditional heavy and manufacturing industries, and an increasing emphasis on a more service industry oriented economy.[78] Tourism has become a significant industry, attracting millions of visitors to England each year. The export part of the economy is dominated by pharmaceuticals, cars (although many English marques are now foreign-owned, such as Land Rover, Lotus, Jaguar and Bentley),crude oil and petroleum from the English parts of North Sea oil along with Wytch Farm, aircraft engines and alcoholic beverages.[136]
