History Of Electronic Communications

Electronic communications is any communication based on electricity. The basis for this wasn’t properly harnessed until both direct current and alternating current electricity were mastered and popularized in the late 19th century. Thomas Edison warned that direct current electricity was safer, and thus should form the basis of a national power company. Unfortunately, alternating current electricity had better transmission capabilities and although it is more dangerous, became the basis for modern electrical power. These basic truths would ultimately form the foundation for modern electronic communication. All communications formed with alternating electrical current will be investigated.

What we know of as electronic communications originated with the telegraph. The telegraph was a simple electrical circuit that transmitted electrical impulses across country via wire. It had two signals, a dot and a dash. This formed a code that could be interpreted as words. This code was Morse code. Over time, the code would be translated into all languages and became state-of-the-art technology. It permitted coast to coast data transmissions and formed the basis for facsimile transmission as well.

The next major communications invention was the telephone. The “plain old telephone” has changed very little since it was invented in the early 19th century. It has just become more popular and accepted since its invention. It was patented by Alexander Gram Bell in 1876 but more than likely invented by Innocenzo Manzetti and was originally called the “speaking telegraph”. The history indicates that the telephone as actually being demonstrated in England some nine years before Alexander Bell filed his patent in America. The idea that the phone was invented in America is a misconception. Regardless of its origins, there was nothing as convenient as the...
