Digital Revolution

The Digital Revolution is the change from analog mechanical and electronic technology to digital technology that has taken place since 1980 and continues to the present day.

Implicitly, the term also refers to the sweeping changes brought about by digital computing and communication technology during the latter half of the 20th century. Analogous to the Agricultural Revolution and Industrial Revolution, the Digital Revolution marked the beginning of the Information Age.

Central to this revolution is the mass production and widespread use of digital logic circuits, and its derived technologies, including the computer, digital cellular phone, and fax machine.

The rise in digital tech use, from 1990 to 2010

1990: Mobile phone subscribers: 12.4 million, Internet users: 2.8 million (0.05% of world population in 1990)

2010: Mobile phone subscribers: 5.2 billion (79% of world population in 2010), Internet users: 1.8 billion (26.6% of world population)

Brief history

The underlying technology was invented in the later half of the 20th century and became economical for widespread adoption after the invention of the Personal Computer. Claude Shannon, a Bell Labs mathematician, is credited for having laid out the foundations of digitalization in his pioneering 1948 article, A Mathematical Theory of Communication.

The digital revolution converted technology that previously was analog into a digital format.

By doing this, it became possible to make multiple generation copies that were identical to the original. In digital communications, for example, repeating hardware was able to amplify the digital signal and pass it on with no loss of information in the signal. Of equal importance to the revolution was the ability to easily move the digital information between media, and to access or distribute it remotely.

A major landmark in the revolution was the transition from analog to digital recorded music.
In the 1980s, the digital format of optical compact discs supplanted analog formats, such asvinyl records and cassette tapes, as the popular medium of choice.

Until this point, this is a Wikipedia text.

My comment, in one sentence, would be:

Since then humanity has never been the same.
