ABSTRACT
A service industry is one that produces intangible goods for customers, in contrast with manufacturing and agricultural industries whose products are physical objects. The world’s nations have developed from largely agricultural economies through manufacturing (following the industrial revolution) to service-based. A developed country will now have service as its largest employment and revenue sector, followed by manufacturing with agriculture a distant third. In addition, our primary industries depend on service companies, for example, to transport our food from producer to consumer, or to raise the capital required to expand manufacturing.
