If you mean the "television", no.
No.
to put on puppet shows before tv was invented
before television was invented :)
Yes, the car was invented first.
No-one.
If you mean President Andrew Jackson, he was long dead before TV was invented
Don't think so
He died before television was invented.
Before
TV's were not discovered. They didn't exist before they were invented.
I assume you mean "why wasn't television invented earlier". Us humans had to learn a certain level of Electronic engineering Before the tv could be invented. Once we were good enough at that, the tv soon followed.
That's a huge question... A lot was invented before TV. If you mean in the field of video, the first form of displaying moving film was actually the projector, because it simply required you to move the frames in front of a strong light source. The TV is far more complicated than that.
