"In recent years, college students have been bringing clickers to lecture halls, where professors require their use for attendance, instant polls and multiple-choice tests. Corporate executives sometimes distribute the devices at meetings, and then show survey responses immediately on Power Point slides. Just two of many companies that make clickers have sold nearly nine million units, which typically cost between $30 and $40 apiece, in under a decade. One the companies, Turning Technologies, sold 1.5 million in 2011 alone. But clickers can now be found in some surprising corners of American life, too, as churches, fire departments, cruise ships and health care providers discover uses for them, essentially spreading the phenomenon of online crowdsourcing to off-line crowds." | via New York Times
