• Joseph John Thomson made the beginning of electronics in 1899 at the University of Cambridge, England by discovering electrons
• In the 20th century, people became more interested in electronics
• Guglielmo Marconi made the first development in electronics by sending a message across the Atlantic Ocean using wireless telegraphy in 1901
• Lee De Forest invented the audion vacuum tube in 1906, which was related to its first use to make sounds ("audio") louder
• Greenleaf W. Pickard used the first crystal radio detector in 1906, which helped make radio and electronics more popular
• Commercial radio was born in Pittsburgh, Pennsylvania at station KDKA in 1920, marking the beginning of a new era
• By 1973, more than half the homes in the USA had a radio
• Commercial Television began around 1946
• In 1947, several hundred thousand home radio receivers were manufactured and sold
• The first vacuum tube was funded by the U.S. government, and research began in 1943
• ENIAC, the Electronic Numerical Integrator and Computer, was formally dedicated at the Moore School of Electrical Engineering of the University of Pennsylvania on February 15, 1946, as the first electronic digital computer
• John Bardeen, Walter H. Brattain, and William B. Shockley, working at Bell Laboratories, made the first working transmission and were awarded the Nobel Prize
• Claude Shannon, also at Bell Laboratories, published a paper on communicating in binary code in 1948
• Claude Shannon first applied Boolean algebra to telephone switching networks and worked at the Massachusetts Institute of Technology in 1940
• Jack Kilby at Texas Instruments led to the development of the integrated circuit in 1958
• A Noyce, working at Fairchild, along with Jack Kilby, shared a Nobel Prize in Physics for inventing the integrated circuit
• Integrated circuits are complex combinations of several kinds of things on a tiny piece of silicon substrate
• The microprocessor reduced most of the circuitry of a computer to a single integrated circuit, some containing the equivalent of billions of transistors
• In 1977, the cellular telephone system entered its testing phase
• In 1982, Texas Instruments offered a single-chip digital signal processor (DSP), which is one of the most rapidly expanding segments of the semiconductor industry
• The integrated circuit has led to an electronics explosion
