It was Martin Cooper who called the world's first mobile phone. At that time, Mr. Cooper, who served as general manager of the communications system division of Motorola, decided to test the phone test of the developed mobile phone in New York City Sixth Avenue. From that size I took out a beige box nicknamed "brick" and extended the antenna with the same length as the main body, Mr. Cooper decided to call from the mobile phone for the first time. At that time it was an era when the cordless home phone was not even used, and New Yorkers sensitive to the trend were also watching Mr. Cooper 's actions all the time.

Mr. Cooper chose Mr. Cooper as a partner with a mobile phone that succeeded for the first time in the world, said AT & T engineer Joe Engel who was rivalry with Motorola. Of course the content I said is, "I'm calling you from my mobile phone, it's a personal portable phone you can carry." Furthermore, Mr. Cooper seems to have also called Dr. Joel Angel of Bell Laboratories, but here it is not telling you that he is calling from a mobile phone, "I am calling to make sure the voice of the new phone is made possible How do you like the sound with your handset? "


It was a mobile phone that made the first call in the 1970s successful, but it took about 10 years to commercialize it. Mobile phone released from Motorola "DynaTAC 8000X"It is almost the same design as Mr. Cooper used for the first call test, and the selling price in 1984 was 3,995 dollars (about 1 million yen at present value). It seems that mobile phones which became commonplace to hold one person each now was a luxury item which only partly rich people could get out at the beginning.


After that, when "Nokia 3210" was released in 1999, we recorded a huge hit to sell 150 million units worldwide, and the era of everyone arriving with mobile phones has arrived. And in 2007, the iPhone which touches the touch is released, the smartphone era begins and it reaches the present at the beginning.
