Radiovision was his term for what we call "television". Television was his term for what we call "cable television".
Radiovision was a broadcast signal. Television was a cable signal. He could not lay out sufficient high grade wire to implement "television".
Radiomovies was his term for closed audience "broadcasts" (at say a theater). This was "pay per view" broadcasts of major sporting events (like boxing). As movies go digital, they will be beamed by satallite to theaters to reduce shipping costs that much more.
Jenkins studied the flapping of a flag on a flagpole and came up with a patent for movie projectors (pre-1900) that kept the film from flapping as it went past the lens. Thomas Edison bought that patent from Jenkins' company and used it to shut down a lot of other projector manufacturers.
There are a lot of inventors who get overlooked. I'll have to look at that website sometime. Looks interesting. I just hope that it doesn't spin the hyperbole of "first" too much.
Philo Farnsworth didn't get the credit he deserved for all electronic TV either, thanks to Sarnoff.
Wasn't there a man in Kentucky who supposedly made the first real radio transmission? (my memory isn't very sharp today, and it's been hard lately for my brain to shift gears into tech mode). I swear, so much of history of electronics is still tainted by the RCA revisionists of the time.
I wonder if George Méliès knew about it when he produced his Long Distance Wireless Photogaraphy in 1908?
