The term BlackBerry refers to a line of wireless handheld devices and services designed and marketed by BlackBerry Limited, formerly known as Research In Motion Limited (RIM). The first BlackBerry device, an email pager, was released in 1999. The most recent BlackBerry devices are the Z3, Z30, Z10 and the newly released Passport. The Z3, Z30 and Z10 were announced on February 2014, September 2013 and January 2013 respectively. The user interface varies by model; most had featured a physical QWERTY keyboard, while newer generations have relied on a multi-touch screen and virtual keyboard.
