The underlying technology was invented in the later half of the 19th century, including Babbage’s analytical engine and the telegraph. The turning point of the revolution was the change from analogue to digitally recorded music. In 1947, the transistor was invented, leading the way to more advanced digital computers. A key step toward mass commercialization was the advent of the planar process in 1959 by Jean Hoerni, an employee of Fairchild Semiconductor.

From 1969 to 1971, Intel developed the Intel 4004, an early microprocessor that laid the foundations for the microcomputer revolution that began in the 1970s. The public was first introduced to the concepts that would lead to the Internet when a message was sent over the ARPANET in 1969. The Whole Earth movement of the 1960s advocated the use of new technology. In developed nations, computers achieved semi-ubiquity during the 1980s as they made their way into schools, homes, business, and industry. 1984, and that households with children under the age of 18 were nearly twice as likely to own one at 15. However, this device used analog communication – digital cell phones were not sold commercially until 1991 when the 2G network started to be opened in Finland to accommodate the unexpected demand for cell phones that was becoming apparent in the late 1980s.

CD-ROM would be the centerpiece of the revolution, with multiple household devices reading the discs. The first true digital camera was created in 1988, and the first were marketed in December 1989 in Japan and in 1990 in the United States. By the mid-2000s, they would eclipse traditional film in popularity. Digital ink was also invented in the late 1980s. 1989’s The Little Mermaid and for all their animation films between 1990’s The Rescuers Down Under and 2004’s Home On The Range. Tim Berners-Lee invented the World Wide Web in 1989. 10 theaters in Spain and Italy.

However HDTV did not become a standard until the mid-2000s outside Japan. The World Wide Web became publicly accessible in 1991, which had been available only to government and universities. Cell phones became as ubiquitous as computers by the early 2000s, with movie theaters beginning to show ads telling people to silence their phones. They also became much more advanced than phones of the 1990s, most of which only took calls or at most allowed for the playing of simple games. Text messaging existed in the 1990s but was not widely used until the early 2000s, when it became a cultural phenomenon. The digital revolution became truly global in this time as well – after revolutionizing society in the developed world in the 1990s, the digital revolution spread to the masses in the developing world in the 2000s.

In late 2005 the population of the Internet reached 1 billion, and 3 billion people worldwide used cell phones by the end of the decade. HDTV became the standard television broadcasting format in many countries by the end of the decade. By 2012, over 2 billion people used the Internet, twice the number using it in 2007. Cloud computing had entered the mainstream by the early 2010s. By 2015, tablet computers and smartphones were expected to exceed personal computers in Internet usage.

It is estimated that the world’s capacity to store information has increased from 2. Conversion of below analog technologies to digital. The decade indicated is the period when digital became dominant form. Disappearance of other technologies also attributed to digital revolution.

Positive aspects include greater interconnectedness, easier communication, and the exposure of information that in the past could have more easily been suppressed by totalitarian regimes. Islamist governments and in Syria a civil war have formed in the absence of the dictatorships that were toppled. The economic impact of the digital revolution has been large. The digital revolution radically changed the way individuals and companies interact. After initial concerns of an IT productivity paradox, evidence is mounting that digital technologies have significantly increased the productivity and performance of businesses. Negative effects include information overload, Internet predators, forms of social isolation, and media saturation. In some cases, company employees‘ pervasive use of portable digital devices and work related computers for personal use—email, instant messaging, computer games—were often found to, or perceived to, reduce those companies‘ productivity.

Privacy in general became a concern during the digital revolution. The ability to store and utilize such large amounts of diverse information opened possibilities for tracking of individual activities and interests. The Internet, especially the WWW in the 1990s, opened whole new avenues for communication and information sharing. The ability to easily and rapidly share information on a global scale brought with it a whole new level of freedom of speech. Small regional companies were suddenly given access to a larger marketplace.

In other cases, special interest groups as well as social and religious institutions found much of the content objectionable, even dangerous. Many parents and religious organizations, especially in the United States, became alarmed by pornography being more readily available to minors. Copyright and trademark issues also found new life in the digital revolution. The widespread ability of consumers to produce and distribute exact reproductions of protected works dramatically changed the intellectual property landscape, especially in the music, film, and television industries. The digital revolution, especially regarding privacy, copyright, censorship and information sharing, remains a controversial topic. As the digital revolution progresses it remains unclear to what extent society has been impacted and will be altered in the future. While there have been huge benefits to society from the digital revolution, especially in terms of the accessibility of information, there are a number of concerns.

Expanded powers of communication and information sharing, increased capabilities for existing technologies, and the advent of new technology brought with it many potential opportunities for exploitation. From the perspective of the historian, a large part of human history is known through physical objects from the past that have been found or preserved, particularly in written documents. Digital records are easy to create but also easy to delete and modify. These problems are further compounded by the use of digital rights management and other copy prevention technologies which, being designed to only allow the data to be read on specific machines, may well make future data recovery impossible.
