The BlackBerry smart mobile phone was introduced in 2000 by the Research In Motion company, based in which country?

BlackBerry Limited is a Canadian multinational company specializing in enterprise software and the Internet of things. Originally known as Research In Motion (RIM), it is best known to the general public as the former developer of the BlackBerry brand of smartphones, and tablets. It transitioned to an enterprise software and services company under CEO John S. Chen.

Its products are used worldwide by various businesses, car makers, and government agencies, and include the AtHoc crisis communications platform, the QNX real-time operating system, and BlackBerry UEM, an endpoint management platform. BlackBerry was founded in 1984 as Research In Motion by Mike Lazaridis and Douglas Fregin.

In 1999, RIM introduced the BlackBerry 850 pager. Named in reference to the resemblance of its keyboard's keys to the druplets of the blackberry fruit, the device could receive push email from a Microsoft Exchange Server using its complementary server software, BlackBerry Enterprise Server (BES). The introduction of the BlackBerry set the stage for future enterprise-oriented products from the company, such as the BlackBerry 957 in April 2000, the first BlackBerry smartphone.
