Very soon after, Sony acquired the rights to transistor production, producing televisions throughout the next decade that would make previous vacuum tube models obsolete.Ī perhaps less obvious impact of transistors is the role they played in early space travel and satellite technology. Texas Instruments (the company which would later spawn the integrated circuit) began the first commercial production of transistors for radios in 1954. The first commercial fully transistorized computer was the IBM 608, first shipped in 1957.Ī similar impact occurred with radios and television. The University of Manchester (United Kingdom) built the first experimental computer that used transistors, first operational in 1953. The invention of this smaller and more energy efficient means of amplifying electrical signals revolutionized the way computers were designed. The first fully transistorized TV was Philco's "Safari".Ĭomputers had been around for just under a decade when transistors were invented. Starting in 1959, vacuum tubes in televisions would be replaced with transistor technology. In Fall 1955, Chrysler announced the first transistorized car radio which was manufactured for them by Philco and available as an option in their 1956 Chrysler Imperial models. Bell Hearing Aids were also one of the early uses of transistors first available to consumers.īy 1954, numerous companies including Regency, Sony & Texas Instruments (under license from Bell Labs) began producing transistorized AM radios for the commercial market. The first use of Transistors was in the Bell Telephone System (United States) around 1953 where they were used in the nation-wide toll dialing program, junction transistors were integrated into the switching equipment that automatically determined direct and alternate routes across the nations telephone networks. However, the three men were all integral to the development of the transistor, which was recognized when they were jointly awarded the 1956 Nobel Prize for their contributions to physics.Īs a result of a 1956 Consent Decree, AT&T was forced to license the patented transistor technology to any company for $25,000. Shockley's later design, the "bipolar junction transistor", was superior and replaced the earlier type. The "point-contact" transistor was composed of two hair-thin wires resting on a small piece of Germanium (a semiconducting metallic element). However, the initial design built by the Brattain and Bardeen, called the "point-contact transistor", was later updated by an improved model designed by Shockley. Brattain and Bardeen came in to actually help Shockley build the physical model, which he had unsuccessfully attempted before. Shockley developed the scientific theory behind the transistor, dedicating nearly a decade of his time to the research. The development of the transistor took place at Bell Labs, the research division of AT&T. There were three important individuals behind the transistor's development, William Brattain, John Bardeen, and William Shockley. In the early 1950's, IBM touted that Transistors only consumed about 1/10th the power and weighed 1/100th as much as equivalent vacuum tubes.ĭecemwas the day the transistor was first successfully tested. Before the era of transistors, having a radio in your home meant acquiring a large piece of furniture. Vacuum tubes were bulky, and they required a lot of power to operate. Prior to transistors, vacuum tubes were the only option to provide this amplification. In order for electronic signals to be transmitted in a device, some other signal needs to amplify and control them. The role of the transistor in the development of electronic devices is similar to that of the integrated circuit. Transistors, which are used to amplify and control electrical current, have played an important role in computing, radio, TV, and even space travel. The transistor was a crucial element in the development of better performing and more accurate electronic devices.
