The first commercially available cell phone was the Motorola DynaTAC, released in 1973. Users eventually nicknamed the DynaTAC “the brick" due to its large size and weight.  Developed by Martin Cooper, the original cell phone allowed users to break away from wired communication and make calls on the go. While it may seem clunky by today's standards, the DynaTAC laid the foundation for more compact and advanced cell phones for future generations.
