BlackBerry was a brand of smartphones and other related mobile services and devices. The line was originally developed and maintained by the Canadian company BlackBerry Limited (formerly known as Research In Motion, or RIM) from 1999 to 2016, after which it was licensed to various companies. Specializing in secure communications and mobile productivity, BlackBerry was once well known for the keyboards on most of its devices and software services that ran through its own servers. At its peak in September 2011, there were 85 million BlackBerry subscribers worldwide. However, BlackBerry lost its dominant position in the market due to the success of the Android and iOS platforms; its numbers had fallen to 23 million in March 2016, a decline of almost three-quarters. On September 28, 2016, BlackBerry Limited announced it would cease designing its own BlackBerry devices in favor of licensing to partners to design, manufacture, and market. The original licensors were BB Merah Putih for the Indonesian market, Optiemus Infracom for the South Asian market, and BlackBerry Mobile (a trade name of TCL Technology) for all other markets. Historically, BlackBerry devices used a proprietary operating system—known as BlackBerry OS—developed by BlackBerry Limited. In 2013, BlackBerry introduced BlackBerry 10, a major revamp of the platform based on the QNX operating system. BlackBerry 10 was meant to replace the aging BlackBerry OS platform with a new system that was more in line with the user experiences of Android and iOS platforms. In 2015, BlackBerry began releasing Android-based smartphones, beginning with the BlackBerry Priv. History Research in Motion (RIM), founded in Waterloo, Ontario, first developed the Inter@ctive Pager 900, announced on September 18, 1996. The Inter@ctive Pager 900 was a clamshell-type device that allowed two-way paging. 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. The first BlackBerry device, the 850, was introduced in 1999 as a two-way pager in Munich, Germany. BlackBerry was a solution devised by RIM for delivering e-mail
