If Radio Corporation of America (RCA) was still in
existence today, undoubtedly they would be running an advertisement mentioning not just radio and television in their list of wireless
communications accomplishments since Marconi's message "first forged in 1901 from the mere sound of three dots," but also cellphones, satellite
navigation (GPS), cable television, and Wi-Fi. Founded in 1919, RCA was bought
by General Electric in 1986 and then subsequently broken into components and sold off to other companies like Sony, NBC (National Broadcasting
Company), and Comcast.
Three dots in Morse Code - sent from England and received by Marconi in Newfoundland - proved that wireless signals could span the Atlantic.
Three dots that opened a new era!
When Marconi, on December 12, 1901, heard a "3-dot" radio signal - the letter "S" in Morse Code - across 1,800 miles of sea, it was an experimental
triumph that opened a new era in communications.
Before this historic event, wireless telegraphy had been limited primarily to communications between the shore and ships at sea. Marconi's
success, however, was the forerunner of many other developments which led eventually to RCA world-wide radiotelegraph service that now operates
more than 80 direct circuits to 66 countries.
As radio progressed, its usefulness was expanded by invention and development of the electron tube, the harnessing of short waves which made
world-wide transmission a reality, and the automatic transmission and reception of messages at high speed.
Radio, with its magic of spoken words and music broadcast over the world ... television, the miracle of pictures in motion transmitted through
the air ... these mediums of modem communication have added notable links in the chain of electronic advances first forged in 1901 from the
mere sound of three dots.
