The Las Vegas that we know today basically began after World War II, when the idea of large hotels along the brand new “strip†was developed. Las Vegas is the “marriage capital†of America; there are 50 wedding chapels in the city. Tourism and the convention industry are the city's major sources of income. In addition, manufacturing, government, warehousing, and trucking are major sources of employment. Many high-technology companies are also located in Las Vegas.
