Period Overview (1896-1927)
General reviews of the individuals, activities and technical advances which characterized this era -
Early Radio Industry Development (1897-1914) -
As with most innovations, radio began with a series of incremental scientific discoveries and technical refinements, which eventually led to the development of commercial applications. But profits were slow in coming, and for many years the largest U.S. radio firms were better known for their fraudulent stock selling practices than for their financial viability. -
Big Business and Radio (1915-1922)
Once the radio industry finally became profitable, major corporations -- including the American Telephone & Telegraph Company, General Electric, and Westinghouse -- moved into the field. Meanwhile, in 1919, due to pressure from the U.S. government, American Marconi's assets were sold to General Electric, which used them to form the Radio Corporation of America. -
Radio at Sea (1891-1922)
The first major use of radio was for navigation, where it greatly reduced the isolation of ships, saving thousands of lives, even though for the first couple of decades radio was generally limited to Morse code transmissions. In particular, the 1912 sinking of the Titanic highlighted the value of radio to ocean vessels. -
Julio Cervera Baviera
developed radio in Spain around 1902.Cervera Baviera obtained patents in England, Germany, Belgium, and Spain. In May–June 1899, Cervera had, with the blessing of the Spanish Army, visited Marconi's radiotelegraphic installations on the English Channel, and worked to develop his own system. He began collaborating with Marconi on resolving the problem of a wireless -
"wireless telegraphy"
The idea of wireless communication predates the discovery of "radio" with experiments in "wireless telegraphy" via inductive and capacitive induction and transmission through the ground, water, and even train tracks from the 1830s on -
Harold J. Power
On March 8, 1916, Harold Power with his radio company American Radio and Research Company (AMRAD), broadcast the first continuous broadcast in the world from Tufts University under the call sign 1XE (it lasted 3 hours). The company later became the first to broadcast on a daily schedule, and the first to broadcast radio dance programs, university professor lectures, the weather, and bedtime stories -
Charles David Herrold
To help the radio signal to spread in all directions, he designed some omnidirectional antennas, which he mounted on the rooftops of various buildings in San Jose. Herrold also claims to be the first broadcaster to accept advertising (he exchanged publicity for a local record store for records to play on his station), though this dubious honour usually is foisted on WEAF -
1873 James Clerk Maxwell
showed mathematically that electromagnetic waves could propagate through free space. It is likely that the first intentional transmission of a signal by means of electromagnetic waves was performed in an experiment by David Edward Hughes around 1880, although this was considered to be induction at the time. In 1888 Heinrich Rudolf Hertz was able to conclusively prove transmitted airborne electromagnetic waves in an experiment confirming Maxwell's theory of electromagnetism
