BlackBerry is a line of smartphones and services designed and marketed by BlackBerry Limited (formerly known as Research In Motion/RIM). The very first RIM device was the Inter@ctive Pager 900, a clamshell-type device that allowed two-way paging, announced on September 18, 1996. After the success of the 900, the Inter@ctive Pager 800 was created for IBM, which bought US$10 million worth of them on February 4, 1998. The next device to be released was the Inter@ctive Pager 950, on August 26, 1998. The very first device to carry the BlackBerry name was the BlackBerry 850, an email pager, released January 19, 1999. Although identical in appearance to the 950, the 850 was the first device to integrate email and the name Inter@ctive Pager was no longer used to brand the device.
