RIM was founded by Mike Lazaridis and is based in Waterloo, Ontario. Before the development of the BlackBerry, RIM worked with RAM Mobile Date and Ericsson, assisting in converting the Ericsson-developed Mobitex wireless data network into a two-way paging and wireless email network.
RIM has gone on to develop many different BlackBerry devices, which have become the smart phone of choice among business and government professionals. So loyal are BlackBerry users that the devices have come to be known as Crackberries, a back-door joke aimed at users who claim they cannot live without them.
Major competitors include Apple Inc., HTC, Palm, Motorola, Samsung and others.
