At the time, Student Response Systems were already in use and he had been using one by Texas Instruments for his class.  Students had to download a software onto their calculator and then vote that way. However, the logistics were not working out and troubleshooting problems would take up most of Stelzer\u2019s time.  Accordingly, Stelzer worked together with a team of professors and a graduate student to develop a response system that would be easy-to-use and inexpensive. They worked on several prototypes for five years until Macmillan, the publishing company, bought the i>clicker in 2005. Since then, the i>clicker has evolved into its own brand, the iClicker. Now, iClicker also offers Reef Education, a mobile-optimized, cloud based education engagement system. Overall, iClickers are simple devices with either six or thirteen buttons and, on certain models, a small screen.
