The Motorola DynaTAC was a series of early [[cellphone]]s produced from 1983 to 1994.  They were very large and bulky compared to most later cellphones (weighing about 2.5 lbs or 1 kg) and could not fold like many later pre-smartphone models.  As such it was commonly given the nickname of a "brick phone".
