BlackBerry Limited is a Canadian multinational company specialising in enterprise software and the Internet of things. Originally known as Research In Motion (RIM), it developed the BlackBerry brand of interactive pagers, smartphones, and tablets. It transitioned to an enterprise software and services company under Chief Executive Officer John S. Chen. Its products are used by various businesses, car makers, and government agencies. They include BlackBerry Cylance's artificial intelligence based cyber-security solutions, the BlackBerry AtHoc emergency communication system (ECS) platform; the QNX real-time operating system; and BlackBerry Enterprise Server (BlackBerry Unified Endpoint Manager), a Unified Endpoint Management (UEM) platform. BlackBerry was founded in 1984 as Research In Motion by Mike Lazaridis and Douglas Fregin. In 1992, Lazaridis hired Jim Balsillie, and Lazaridis and Balsillie served as co-CEOs until January 22, 2012, when Thorsten Heins became president and CEO. In November 2013, John S. Chen took over as CEO. His initial strategy was to subcontract manufacturing to Foxconn, and to focus on software technology. Currently, his strategy includes forming licensing partnerships with device manufacturers such as TCL Communication and unifying BlackBerry's software portfolio.
