BONUS QUESTION:
What nationality can legitimately claim Radio broadcasting, the

These inventions were in development by many people, and some may have
built on ideas from others.

The light bulb is a good example. Edison is credited by many, but in
looking at the issue in more detail, you will find that he bought a
patent from a Canadian inventor, who had the essential idea, and was
perhaps 90 percent of the way to a practical product. Edison then
perfected the filament and gas in the container. So who was the inventor?
The one with the original idea, or the one who finally made a saleable
product?

What Edison excelled at, was making practical use of his inventions, and
in marketing.

The radio is another example. A number of people were working on various
designs, and Nicola Tesla is the one who holds the first patent for a
tuneable circuit, which he used to wirelessly transmit information from
one place to another in expositions. Tesla was not good at marketing his
inventions, unlike Edison, or Marconi, so even though he has claim to the
technology, he really didn't do anything practical with it.

Since the question about radio was related to "broadcasting", the credit
generally goes to Reginald Fessenden, a Canadian, who did much of his
experimental work near Kitty Hawk. (Had to get an oblique reference to
aviation in my post) While Marconi believed code was transmitted through
ether, and marketed point-to-point communication, Fessenden understood
radio waves, and developed the first transmitter for voice. He made the
first "broadcast", using his designs, and intended for more than one
receiver, in 1906.
