In the first 90 seconds, the narration refers to "the insane 19th century electronics that made color possible", but is referring to the 1900s, which were the 20th century.

The video contains no insight at all into "why" color TV was so difficult. It just lists and describes a few key advancements.

Also the "invention" of color TV is very different from the commercialization.

Before Youtube and Wikipedia there used to be a great website I liked to read about Philo Farnsworth but cannot remember the name of it for the life of me now

I grew quite an appreciation of color TV recently when I made a software-defined SECAM decoder. It's mind-boggling that they were able to do this with 60s technology, to be honest. But then what do I know, analog electronics is witchcraft to me :D

Tintin readers will remember the pains suffered by viewers of early color TV experiments (“The Castafiore Emerald”, 1961).
