The birth of modern computing was in the 1970s. The world's first general microprocessor — the Intel 4004, came out on Nov. 1971. The C programming language was developed early in the decade with the Unix operating system being rewritten into it in 1973. With "large-scale integration" possible for integrated circuits (microchips) rudimentary personal computers began to be produced along with pocket calculators. Notable home computers released in North America of the era are the Apple II, the TRS-80, the Commodore PET, and Atari 400/800 and the NEC PC-8001 in Japan.
The availability of affordable personal computers led to the first popular wave of internetworking with the first bulletin board systems. In 1976, Cray Research, Inc. introduced the first supercomputer, the Cray-1, which could manipulate operations at a rate of 240,000,000 calculations per second. Supercomputers designed by Cray continued to dominate the market throughout the 1970s. The 1970s was also the beginning of the video game era. Atari established itself as the dominant force in home video gaming, first with its home version of the arcade game Pong and later in the decade with the Atari 2600 console (originally called the "VCS", or Video Computer System). By the end of the decade, the scene was set for the Golden Age of Arcade Games.
The 1970s were also the start of Fiber Optics. In 1970 Corning glass announced that it had created a glass fiber so clear that it could be used to communicate pulses of light. Soon after, GTE and AT&T began experiments to transmit sound and image data using fiber optics, which transformed the communications industry. In automotive technology, post 1973, saw direction in both the United States and Europe turn away from the large and heavy mainstream automobiles, and towards lightweight, fuel efficient and environmentally conscious vehicles, already started to be produced by Japan. The Lotus Esprit was an example of a 1970s super car, producing high performance from a small engine. The Volkswagen Golf GTI of 1974 made the concept of a performance hatchback part of automotive mainstream thinking, though it had many precedents.
The United States lagged badly in the development of compact and fuel-efficient vehicles, a side effect of industrial inexperience on the part of the manufacturers in Detroit, and two giants of the industry, GM and Ford both produced vehicles that fell drastically short of customer desires and economic demands; In the case of GM the Vega and for Ford the Pinto.
Automotive historians have also described the period as 'the era of poor quality control', and manufacturers internationally produced vehicles that have now become by-words for poor technological integration. Notably, the 1970s saw the introduction in the automotive field of novel technologies, particularly from Japan and Germany, that would begin to mature in the 1990s and 2000s as viable alternative propulsion sources, such as hybrid vehicles, Stirling engines, as well as solar-electric and pure-electric vehicles.
The integration of the computer and robot, particularly in Japan, saw unprecedented improvements in mass-produced automotive quality. Japanese advanced lightweight, fuel efficient and environmentally conscious vehicles dramatically increased in demand, and such cars as the Honda Civic and the Toyota Corolla became some of the most popular and iconic vehicles of the 1970s. Japanese manufacturers dramatically made their presence felt in international markets during the decade.
During the 1970s, microwave ovens experienced a surge in popularity as price and size decreased rapidly towards the end of the decade. Cassette tapes also continued to surge in popularity after their introduction in the 1960s. JVC's VHS and Sony's Betamax waged a war as the primary recording and video devices beginning in 1976, but by the end of the decade VHS had become the dominant format.
