The history of the Internet as we know it goes back about 30 years. However, there is a technology that has a more respectable age. Year 2021 it's golden anniversary of electronic mail. First ever email was sent in 1971 by Ray Tomlinson , an engineer at the BBN company. The story goes that he did not create new software for these purposes, but managed to properly use several utilities for the ARPANet network, the precursor to the Internet. Electronic message was successfully transferred between neighboring computers. Legend has it that the message read as follows: "QWERTYUIOP". Also, noteworthy that Tomlinson first used '@' symbol in his early system. Internet technologies continue to evolve, but we are also taking advantage of inventions that were made 50 years ago.  Happy golden anniversary, Email!
