And now, a visual history marking the accomplishments of mobile phones, from military applications to mobile apps. Alexander Graham Bell would surely be proud.
EVOLUTION OF CELL PHONE
Forty years ago today, Motorola engineer Martin Cooper — credited as the inventor of the cell phone — made the world's first public call from a mobile phone, choosing to get in touch with his rival in the race to create the device.

Since then, cell phones have been rapidly evolving into the high-tech multitasking devices we use today. Here is a look at some of the most famous developments in mobile phone history.
