It's sixty years since the first portable transistor radio went on the market and started a revolution Sony, who is often credited with developing the first portable radio, didn't come out with theirs until 1957. Don Pies Regency TR1 Website/via. It didn't take long for transistors to take over and for them to shrink down to integrated circuits to the point where you can now get an entire Radio Shack in an iPhone. It all started 60 years ago with this.

Who invented the radio? Meanwhile, Marconi had been conducting his own experiments and in 1896, sent and received Morse code-based radio signals at distances spanning nearly 4 miles (6 kilometers) in England. That same year, he applied for, and was granted, the world's first patent in wireless telegraphy in England [source: Nobel Prize ].Tesla applied for his first patents in radio work in 1897 in America.ut more than 100 years later, ask any two people who invented the radio and you're likely to get two different answers. The story is a murky one that mixes scientific discovery with lawsuits and good old-fashioned marketing. Let's see if we can untangle the threads.

Transistor radio The typical portable tube radio of the fifties was about the size and weight of a lunchbox, and contained several heavy, non-rechargeable batteries— one or more so-called A batteries to heat the tube filaments and a large 45- to 90-volt B battery to power the signal circuits.

Ham Radio History Ham Radio History In 1873, James Clerk Maxwell presented his theory of the electromagnetic field. In 1901 Guglielmo Marconi communicated across the Atlantic with a radio device using high power and giant antennas. To curb interference, Congress approved the Radio Act of 1912, which required amateurs to be licensed and restricted to the single wavelength of 200 meters.

- Later Marconi set up long-distance demonstrations, using a Tesla oscillator to transmit the signals across the English Channel. Tesla filed his own basic radio patent applications in 1897. They were granted in 1900. Marconi's first patent application in America, filed on November 10, 1900, was turned down. Marconi's revised applications over the next three years were repeatedly rejected because of the priority of Tesla and other inventors.

- 1947: Invention of the Transistor. The first transistor was invented at Bell Laboratories on December 16, 1947 by William Shockley (seated at Brattain's laboratory bench), John Bardeen (left) and Walter Brattain (right).he picture on the left above shows the first point contact transistor built by Walter Brattain. It consisted of a plastic triangle lightly suspended above a germanium crystal which itself was sitting on a metal plate attached to a voltage source.

That same year, he applied for, and was granted, the world's first patent in wireless telegraphy in England [source: Nobel Prize ].esla's radio patents gave him ownership over one of the key necessities in radio communications. That same year, on Nov. 10, Marconi filed patent No. 7777, for tuned telegraphy. At first the patent office denied Marconi's applications on the grounds that his work relied on the use of Tesla coils [source: PBS ].

Who Invented the Radio? Unraveling its History Right Here Nikola Tesla did file for the first patent of inventing the radio in 1897, which was granted to him in the United States in 1900. Marconi too filed for a patent in USA in the same year (1900), as the first inventor of the radio.he question as to who invented the radio does not have a specific answer. There have been numerous theories and patents filed for credits. In case of the discovery of the radio, one fine understanding is that many theories and principles went into a completed circuit of the radio.

What is a Transistor? The first IC was constructed in 1971. Since that year, transistors have gotten smaller and smaller such that the amount fit into an IC has doubled roughly every two years, a trend dubbed as “ Moore’s Law .” In the time between then and now, computers have permeated virtually aspect of modern life.
