CAREER OPPORTUNITY: All those apps being made for smartphones, computer tablets and Facebook's online social network are helping the U.S. economy lower its unemployment rate. A study released Tuesday by the technology trade group TechNet estimates apps are responsible for creating about 466,000 U.S. jobs since 2007.
MORE JOBS TO COME: TechNet thinks the so-called "app economy" is still in the early stages of a boom likely to last for many more years as the number of Internet-connect devices and household appliances escalates.
HOT SPOTS: The highest concentration of app jobs is the San Francisco Bay area and in New York.
