When was televison made?
The first operational television was demonstrated publicly by
John Logie Baird in Selfridges, a London department store in March
1925. After improvements to the system, the BBC adopted it and
began public broadcasting with Baird's system in 1929. The
"Televisor" as it was called, used a spinning disc to create an
image so it became the first electro-mechanical television.
In the US, Philo Farnsworth is credited with inventing the first
completely electronic television, which he demonstrated in 1929.
His development removed the mechanical components of televisions
and was used when RCA began the first commercial broadcasts of
television in 1939 in the US.
