July 10 In Radio History


In 1856…Nicola Tesla was born.

Nikola Tesla
Tesla was a Serbian American  inventor, electrical engineer, mechanical engineer, and futurist best known for his contributions to the design of the modern alternating current (AC) electricity supply system.

Tesla's theories on the possibility of the transmission by radio waves go back as far as lectures and demonstrations in 1893 in St. Louis, Missouri, the Franklin Institute in Philadelphia, Pennsylvania, and the National Electric Light Association.  Tesla's demonstrations and principles were written about widely through various media outlets.  Many devices such as the Tesla Coil were used in the further development of radio.

Tesla's radio wave experiments in 1896 were conducted in Gerlach Hotel (later renamed The Radio Wave building), where he resided.

In 1898, Tesla demonstrated a radio-controlled boat—which he dubbed "teleautomaton"—to the public during an electrical exhibition at Madison Square Garden.  The crowd that witnessed the demonstration made outrageous claims about the workings of the boat, such as magic, telepathy, and being piloted by a trained monkey hidden inside.  Tesla tried to sell his idea to the U.S. military as a type of radio-controlled torpedo, but they showed little interest.   Remote radio control remained a novelty until World War I and afterward, when a number of countries used it in military programs.   Tesla took the opportunity to further demonstrate "Teleautomatics" in an address to a meeting of the Commercial Club in Chicago, whilst he was travelling to Colorado Springs, on 13 May 1899.

In 1900, Tesla was granted patents for a "system of transmitting electrical energy" and "an electrical transmitter." When Guglielmo Marconi made his famous first-ever transatlantic radio transmission in 1901, Tesla quipped that it was done with 17 Tesla patents. This was the beginning of years of patent battles over radio with Tesla's patents being upheld in 1903, followed by a reverse decision in favor of Marconi in 1904. In 1943, a Supreme Court of the United States decision restored the prior patents of Tesla, Oliver Lodge, and John Stone.  The court declared that their decision had no bearing on Marconi's claim as the first to achieve radio transmission, just that since Marconi's claim to certain patents were questionable, he could not claim infringement on those same patents  (there are claims the high court was trying to nullify a World War I claim against the U.S. government by the Marconi Company via simply restoring Tesla's prior patent).


In 1933…the first police radio system was put into operation in Eastchester Township, New York


In 1950…After 15 years as a radio favorite, "Your Hit Parade" started a nine-year run on television – the first eight years on NBC, the last year on CBS – while continuing on radio until 1955.

   
                    
In 1954…Radio station WINS in New York City hired disc jockey Alan Freed from WJW in Cleveland, where he had helped popularize, if not invent, the term "rock 'n' roll." 


In  1962…Telstar 1 launched. Telstar is the name of various communications satellites. 

The first two Telstar satellites were experimental and nearly identical. 

Telstar 1 was launched on top of a Thor-Delta rocket on July 10, 1962. It successfully relayed through space the first television pictures, telephone calls, fax images and provided the first live transatlantic television feed. Telstar 2 was launched May 7, 1963. 

Telstar 1 and 2, though no longer functional, are still in orbit as of October 2013.




In 1965...the Rolling Stones got their first Number One U.S. hit with "(I Can't Get No) Satisfaction."
