What was the first tv made and by who?

It was Scotsman John Logie Baird who invented his transmitters and recievers and sets - the receiver and the set were separate - (or Televisors) as he called them in 1928. The first electronic television was invented by Marconi and Issac Shoenberg, Marconi made the transmitter where as Shoenberg and his team made the recievers.

Since this question is in Cable Television, John Logie Baird invented that too.
